Quentin Jacobsen has spent a lifetime loving the magnificently adventurous Margo Roth Spiegelman from afar. So when she cracks open a window and climbs back into his life — dressed like a ninja and summoning him for an ingenious campaign of revenge — he follows.

After their all-nighter ends and a new day breaks, Q arrives at school to discover that Margo, always an enigma, has now become a mystery. But Q soon learns that there are clues — and they’re for him. Urged down a disconnected path, the closer he gets, the less Q sees of the girl he thought he knew.

Despite the tumor-shrinking medical miracle that has bought her a few years, Hazel has never been anything but terminal, her final chapter inscribed upon diagnosis. But when a gorgeous plot twist named Augustus Waters suddenly appears at Cancer Kid Support Group, Hazel's story is about to be completely rewritten.

Before. Miles "Pudge" Halter's whole existence has been one big nonevent, and his obsession with famous last words has only made him crave the "Great Perhaps" (François Rabelais, poet) even more. He heads off to the sometimes crazy, possibly unstable, and anything-but-boring world of Culver Creek Boarding School, and his life becomes the opposite of safe. Because down the hall is Alaska Young. The gorgeous, clever, funny, sexy, self-destructive, screwed-up, and utterly fascinating Alaska Young, who is an event unto herself. She pulls Pudge into her world, launches him into the Great Perhaps, and steals his heart.

After. Nothing is ever the same.

Katherine V thought boys were gross
Katherine X just wanted to be friends
Katherine XVIII dumped him in an e-mail
K-19 broke his heart
When it comes to relationships, Colin Singleton's type happens to be girls named Katherine. And when it comes to girls named Katherine, Colin is always getting dumped. Nineteen times, to be exact.

On a road trip miles from home, this anagram-happy, washed-up child prodigy has ten thousand dollars in his pocket, a bloodthirsty feral hog on his trail, and an overweight, Judge Judy-loving best friend riding shotgun--but no Katherines. Colin is on a mission to prove The Theorem of Underlying Katherine Predictability, which he hopes will predict the future of any relationship, avenge Dumpees everywhere, and finally win him the girl. Love, friendship, and a dead Austro-Hungarian archduke add up to surprising and heart-changing conclusions in this ingeniously layered comic novel about reinventing oneself.

Sparkling white snowdrifts, beautiful presents wrapped in ribbons, and multicolored lights glittering in the night through the falling snow. A Christmas Eve snowstorm transforms one small town into a romantic haven, the kind you see only in movies. Well, kinda. After all, a cold and wet hike from a stranded train through the middle of nowhere would not normally end with a delicious kiss from a charming stranger. And no one would think that a trip to the Waffle House through four feet of snow would lead to love with an old friend. Or that the way back to true love begins with a painfully early morning shift at Starbucks. Thanks to three of today’s bestselling teen authors—John Green, Maureen Johnson, and Lauren Myracle—the magic of the holidays shines on these hilarious and charming interconnected tales of love, romance, and breathtaking kisses.

One cold night, in a most unlikely corner of Chicago, two teens—both named Will Grayson—are about to cross paths. As their worlds collide and intertwine, the Will Graysons find their lives going in new and unexpected directions, building toward romantic turns-of-heart and the epic production of history’s most fabulous high school musical.

Hilarious, poignant, and deeply insightful, John Green and David Levithan’s collaborative novel is brimming with a double helping of the heart and humor that have won both of them legions of faithful fans.
