In The Omnivore's Dilemma, Michael Pollan writes about how our food is grown -- what it is, in fact, that we are eating. The book is really three in one: The first section discusses industrial farming; the second, organic food, both as big business and on a relatively small farm; and the third, what it is like to hunt and gather food for oneself. And each section culminates in a meal -- a cheeseburger and fries from McDonald's; roast chicken, vegetables and a salad from Whole Foods; and grilled chicken, corn and a chocolate soufflé (made with fresh eggs) from a sustainable farm; and, finally, mushrooms and pork, foraged from the wild.

The first section is a wake-up call for anyone who has ever been hungry. In the United States, Pollan makes clear, we're mostly fed by two things: corn and oil. We may not sit down to bowls of yummy petroleum, but almost everything we eat has used enormous amounts of fossil fuels to get to our tables. Oil products are part of the fertilizers that feed plants, the pesticides that keep insects away from them, the fuels used by the trains and trucks that transport them across the country, and the packaging in which they're wrapped. We're addicted to oil, and we really like to eat.

Oil underlines Pollan's story about agribusiness, but corn is its focus. American cattle fatten on corn. Corn also feeds poultry, pigs and sheep, even farmed fish. But that's just the beginning. In addition to dairy products from corn-fed cows and eggs from corn-fed chickens, corn starch, corn oil and corn syrup make up key ingredients in prepared foods. High-fructose corn syrup sweetens everything from juice to toothpaste. Even the alcohol in beer is corn-based. Corn is in everything from frozen yogurt to ketchup, from mayonnaise and mustard to hot dogs and bologna, from salad dressings to vitamin pills. "Tell me what you eat," said the French gastronomist Anthelme Brillat-Savarin, "and I will tell you what you are." We're corn.

Each bushel of industrial corn grown, Pollan notes, uses the equivalent of up to a third of a gallon of oil. Some of the oil products evaporate and acidify rain; some seep into the water table; some wash into rivers, affecting drinking water and poisoning marine ecosystems. The industrial logic also means vast farms that grow only corn. When the price of corn drops, the solution, the farmer hopes, is to plant more corn for next year. The paradoxical result? While farmers earn less, there's an over-supply of cheap corn, and that means finding ever more ways to use it up.

Is eating all this corn good for us? Who knows? We think we've tamed nature, but we're just beginning to learn about all that we don't yet know. Ships were once provided with plenty of food, but sailors got scurvy because they needed vitamin C. We're sailing on the same sea, thinking we're eating well but still discovering nutrients in our food that we hadn't known were there -- that we don't yet know we need.

We've lost touch with the natural loops of farming, in which livestock and crops are connected in mutually beneficial circles. Pollan discusses the alternatives to industrial farming, but these two long (and occasionally self-indulgent) sections lack the focus and intensity -- the anger beneath the surface -- of the first. He spends a week at Joel Salatin's Polyface Farm in the Shenandoah Valley, a farm that works with nature, rather than despite it. Salatin calls himself a grass farmer, though his farm produces cows, chickens, eggs and corn. But everything begins with the grass: The cows nibble at it at the precise moment when it's at its sweetest and are moved from pasture to pasture to keep the grass at its best height. Their droppings fertilize the grass, and the cycle is under way. There's a kind of lyrical symmetry to everything that happens on this farm. Even the final slaughtering of chickens is done quickly and humanely, in the open air. It isn't pleasant, but compared to the way cattle are fattened and slaughtered in meat industry feedlots and slaughterhouses, it is remarkably reasonable.

We needn't learn how to shoot our own pigs, as Pollan does; there's hope in other ways -- farmers' markets, the Slow Food movement, restaurants supplied by local farms. To Pollan, the omnivore's dilemma is twofold: what we choose to eat ("What should we have for dinner?" he asks in the opening sentence of his book) and how we let that food be produced. His book is an eater's manifesto, and he touches on a vast array of subjects, from food fads and taboos to our avoidance of not only our food's animality, but also our own. Along the way, he is alert to his own emotions and thoughts, to see how they affect what he does and what he eats, to learn more and to explain what he knows. His approach is steeped in honesty and self-awareness. His cause is just, his thinking is clear, and his writing is compelling.

Be careful of your dinner!

What if everything you think you know about Jesus is wrong? In The Jesus Papers, Michael Baigent reveals the truth about Jesus's life and crucifixion. Despite -- or rather because of -- all the celebration and veneration that have surrounded the figure of Jesus for centuries, Baigent asserts that Jesus and the circumstances leading to his death have been heavily mythologized.

As a religious historian and a leading expert in the field of arcane knowledge, Baigent has unequaled access to hidden archives, secret societies, Masonic records, and the private collections of antiquities traders and their moneyed clients. Using that access to full advantage, Baigent explores the religious and political climate in which Jesus was born and raised, examining not only the conflicts between the Romans and the Jews, but the strife within the different factions of the Jewish Zealot movement. He chronicles the migrations of Jesus's family, his subsequent exposure to other cultures, and the events, teachings, and influences that were most likely to have shaped his early years. Baigent also uncovers the inconsistencies and biases in the accounts of the major historians of Jesus's time, including Josephus, Pliny, and Tacitus. The enduring influence of these accounts in forming our most common conceptions of Jesus reveals that spin is not a new phenomenon.

Taking us back to sites that over the last twenty years he has meticulously explored, studied, and in some instances excavated for the first time, Baigent provides a detailed account of his groundbreaking discoveries, including many never-before-seen photos. The evidence he has uncovered has lead him to make shocking new assertions that threaten the conventional account of Jesus's life and death and shake the very foundation of Western thought, based as it is upon the assumption of Jesus's divinity. Ultimately, his investigation raises the hope that we may gain a new understanding of Jesus.

Greek myths are among the most complex and influential stories ever told. From the first millennium BC until today, the myths have been repeated in an inexhaustible series of variations and reinterpretations. They can be found in the latest movies and television shows and in software for interactive computer games.

• "Contexts, Sources, Meanings" describes the main literary and artistic sources for Greek myths, and their contexts, such as ritual and theater.
• "Myths of Origin" includes stories about the beginning of the cosmos, the origins of the gods, the first humans, and the founding of communities.
• "The Olympians: Power, Honor, Sexuality" examines the activities of all the main divinities.
• "Heroic exploits" concentrates on the adventures of Perseus, Jason, Herakles, and other heroes.
• "Family sagas" explores the dramas and catastrophes that befall heroes and heroines.
• "A Landscape of Myths" sets the stories within the context of the mountains, caves, seas, and rivers of Greece, Crete, Troy, and the Underworld.
• "Greek Myths after the Greeks" describes the rich tradition of retelling, from the Romans, through the Renaissance, to the twenty-first century.
