Adam Jay Epstein grew up in Great Neck, New York, and started his daydreaming at an early age. After graduating from Wesleyan University, he moved to Los Angeles to start sharing his daydreams with other people. While there, he met a brilliant and creative genius and asked him if he would be interested in becoming one half of a writing team. When the said genius turned him down, he found the less talented but far more willing Andrew Jacobson to partner with.

Adam Jay Epstein has explored the Amazon, climbed the Great Wall of China, swum with dolphins, and found the best tamales north of the Mexico border. He lives with his wife, Jane, and his two daughters, Penny and Olive. He has a black-and-white alley cat with bite out of his ear living in his backyard.

The Familiars is his first book — with many more to come in the future. 

Andrew Jacobson was born in Milwaukee, Wisconsin. Although he has been living in Los Angeles for the last 10 years, he is still a die-hard Green Bay Packers fan. The first book Andrew remembers reading was Roald Dahl's Charlie and the Charlie Factory, mostly because his second-grade teacher let him eat a Milky Way candy bar while reading it in class every day. The first movie Andrew ever saw in a theater was the 1982 re-release of Star Wars. He loved making up elaborate stories for his action figures as a kid, and still can't believe he figured out a way to turn that into his job. The Familiars is his first novel, coauthored with his long-time writing partner, Adam Jay Epstein.
