Get Ready, Because December's Best YA Books Include Second-Chance Romances and Vampires

Vampires are making a major comeback this month thanks to a sapphic supernatural love story and the latest installment in bestselling author Renée Ahdieh's The Beautiful Quartet, but they're far from the only creatures making a splash in December's must-read YA books. There's also a spooky army base that might just be home to some monsters, a bit of metaphysical time-traveling action, and two women sparring over a literal heart in a far-flung world. Looking for something a little more contemporary? There's no shortage of swoon-worthy romances on offer this month, too. As always, the YA category remains a veritable smorgasbord of genres, and December's bounty is well worth sampling.
