About the book: 2015 / A new fun and enjoyable book from the bestselling author of “The Fault in Our Stars” and “Paper Towns.” Child prodigy Colin Odinets has just graduated from high school and is depressed. Together with his best friend Hassan, he goes on an unforgettable journey that will change his life forever. Friends will have to experience amazing adventures, deduce the formula for romantic relationships, fight, fall in love, be disappointed, discover the secret of numerous Catherines and, finally, become truly happy. The real charm of this book is in the characters of the main characters - life-affirming, smart, not fitting into social boundaries – and in dialogues. In John Green's books, dialogue is a weapon that will blow the reader away.
