Heart of Stone by David W. Burns
With snakes for hair and a gaze that turns men to stone, Kyra Anastas is a modern-day Medusa hiding in Chicago, making her living as a hitwoman. Feared even by other monsters, Kyra lives a bitter existence. But when a dying billionaire asks Kyra to protect her daughter from supernatural dangers, Kyra is given the chance to be something more than just a dealer of death.
Now Kyra is on the run from mythological killers who will stop at nothing to destroy the girl. With nightmares like a Manticore stalking them through the stadium during a basketball game, a Basilisk turning dinner into a death trap, and a Siren popping out of her bathtub, Kyra finds no place is safe. As the assassins close in, Kyra realizes her only chance is if she faces all her demons. Purchase at https://bit.ly/44e8NmK.
