Taken for Granite by Nancey Cummings

A gargoyle imprisoned.
Captured, starved and blinded, Tas hates humans. For eighty agonizing years, he’s plotted all the gruesome ways to exact his vengeance. Then one day his captors to make a fatal mistake. When the door to his cage opens, he’s ready to destroy the human on the other side.
But a different instinct takes over when he scents the female. His mouth waters and his fangs ache, demanding he make the fearless female his.
A single mom, desperate to save her kid.
Juniper owes a lot of money to a very bad man and unless she does what he wants, he’ll hurt her kid.
To clear her debt, all she has to do is drive a van and not ask questions. But when she hears a voice in the back, she realizes she may not only be a thief but also a kidnapper, and that’s where she draws the line.
What she finds in the back isn’t the loot she expected, but it also isn’t a person.
It’s a gargoyle… who intends to claim her as his mate.
