The Sun and the Void

When Reina arrives at Aguila Manor, her heart stolen from her chest, she's on the
verge of death—until her estranged grandmother, a sorceress in the Don's employ,
intervenes. Indebted to a woman she never knew and smitten with Celeste, the
daughter of the house, Reina will do anything to earn the family's favour—even the
bidding of the ancient god who speaks to her from the Manor's foundations.
