Jamie Watson has always been intrigued by Charlotte Holmes; after all, their great-great-great-grandfathers are one of the most infamous pairs in history. But the Holmes family has always been odd, and Charlotte is no exception. She’s inherited Sherlock’s volatility and some of his vices—and when Jamie and Charlotte end up at the same Connecticut boarding school, Charlotte makes it clear she’s not looking for friends.
But when a student they both have a history with dies under suspicious circumstances, ripped straight from the most terrifying of the Sherlock Holmes stories, Jamie can no longer afford to keep his distance. Danger is mounting and nowhere is safe—and the only people they can trust are each other.
Ever since she used the Firebird, her parents' invention, to cross through to alternate dimensions, Marguerite has caught the attention of enemies who will do anything to force her into helping them dominate the multiverse—even hurt the people she loves. She resists until her boyfriend, Paul, is attacked, and his consciousness is scattered across multiple dimensions.
The hunt for each splinter of Paul's soul sends Marguerite racing through a war-torn San Francisco, the criminal underworld of New York City, and a glittering Paris where another Marguerite hides a shocking secret. Each dimension brings Marguerite one step closer to rescuing Paul. But with every trial she faces, she begins to question the one constant she's found between the worlds: their love for each other.
