Designed as exercises in decision-making, these riveting titles each offer 13 choices, such as whether it would be better to be raised by wild dogs or by monkeys, to eat haggis or to hunt and eat woolly mammoth, or to swim like Michael Phelps or run like Usain Bolt. Each pairing features large, relevant, color photos and text boxes that highlight facts about both options and several pro or con observations (e.g., "Bolt trains up to five hours a day."). Cranking up both the value and the fun, each volume ends with two pages of "Lightning Round" dilemmas ("Would you choose to be eaten by your mother like a scorpion or by your mate like a praying mantis?").
