Thrall (The Rade #3)
Katey Hawthorne

August Minotte should’ve been trained as a hereditary witch, but instead he was forbidden to use the grimoires his infamous grandmother left him. The Minottes lost a huge fortune for mysterious reasons, and now Augie’s barely keeping his head -- and his dwindling family -- above water. When he finds a spell to get back their lost riches, he’s just desperate enough to use it. Then the spell summons and enthralls a beautiful, spicy fairy rockstar instead delivering a long-lost pile of money.
They’ll both have to face their families’ dark histories to set Wren free. Then, and only then, they can think about acting on all this pent-up attraction that’s driving them both absolutely wild.
