Disillusioned with college, Everett takes a position teaching philosophy to kids at an innovative summer enrichment academy on an island off the New England coast. The academy is run by fellow student Juniper’s Aunt Laura, and at Laura’s recommendation, Everett uses as his curriculum an exploration of the concept of happiness as described by ten of history’s most significant philosophers. This idea is sparked by a collection of readings saved by Laura’s grandmother, a teacher who originally owned the mansion in which the academy is housed. But along with those readings is a set of clues that lead to a rare historic work by an ancient Greek philosopher—a codex—that is hidden in the mansion. So Everett sets to work preparing the readings for his students while simultaneously solving the clues with Juniper to find the codex.

What Everett doesn’t know, however, is that he and Juniper are not the only ones on the hunt for the codex, and the stakes are high. The book is extremely valuable, and there are plenty of people who would like to get their hands on the money it would bring at auction, including the people who are funding Laura’s academy. The question of rightful ownership and the mystery of the codex’s location deepen as Everett and Juniper solve the riddles to find the keys that will open whatever safe contains the ancient text. And all the while, Everett finds himself falling for Juniper.

He’s also working through the collection of philosophical readings about happiness, taking each one in turn and presenting it in clear, concise, modern English to his students, who are eager to discover how to lead a happy life. Everett is equally eager to make the same discovery, and he carefully considers each philosopher’s thinking on the matter, applying the concepts to his own life in an effort to understand them in the context of a young person in the real world struggling to figure out what he wants to do with his future.

As Everett gains clarity on what he wants out of life, however, the mystery of the codex takes a dark turn, and everything he thought he knew is turned upside down. Who will end up with the codex? What will happen to the academy? And will Everett be able to take everything that he has learned—both the good and the bad—to build a life for himself that will bring him the most happiness?
