From Goodreads about Keystone:
Nalena Maxwell has been branded ‘The Waste’ at her new school, due to her mom's obsessive paper hoarding. Nalena desperately wants something to change in her life, but when she receives a sign (and it's the wrong dang one) inviting her into a mysterious, ancient community, too much changes. What she knew of her family, what she thought of her life and what she believed about her future, is no longer applicable. Seventeen years worth of family skeletons come crashing into Nalena's life and it is the boy...the one that smiles at her like he wants to hear everything she'll ever say...that already knows her powerful secrets. But it is only Nalena that can choose between protecting the life that is already crumbling beneath her feet and the one that might sacrifice everything she could ever have.
