Borrowed Souls by Chelsea Mueller (Soul Charmer #1)BORROWED SOULS (Soul Charmer #1)

A young woman with a brother who can’t stay out of trouble dives head first into the grimy world of soul renting in this action-packed and sexy urban fantasy debut.

Callie Delgado always puts family first, and unfortunately her brother knows it. She’s emptied her savings, lost work, and spilled countless tears trying to keep him out of trouble, but now he’s in deeper than ever, and his debt is on Callie’s head. She’s given a choice: do some dirty work for the mob, or have her brother returned to her in tiny pieces.

Renting souls is big business for the religious population of Gem City. Those looking to take part in immoral—or even illegal—activity can borrow someone else’s soul, for a price, and sin without consequence.

To save her brother, Callie needs a borrowed soul, but she doesn’t have anywhere near the money to pay for it. The slimy Soul Charmer is willing to barter, but accepting his offer will force Callie into a dangerous world of magic she isn’t ready for.

With the help of the guarded but undeniably attractive Derek—whose allegiance to the Charmer wavers as his connection to Callie grows—she’ll have to walk a tight line, avoid pissing off the bad guys, all while struggling to determine what her loyalty to her family’s really worth.

Losing her brother isn’t an option. Losing her soul? Maybe.

“Fun, heartfelt, and wildly creative, Borrowed Souls packs a new brand of punch in a debut urban fantasy with a soulful twist on magic. Determined heroine Callie Delgado will do anything to save her brother from the mob, including a deal with a devilish man, and working with a brooding stranger who is sin in a leather jacket. Author Chelsea Mueller brings a new and exciting voice to the UF genre.”

Kelly Meding

Author of the Dreg City Series

“Fans of UF aren’t going to want to miss this debut novel by Chelsea Mueller! The world building is rich and vibrant and the characters are multi-dimensional. The story is faced paced and engaging with tons of great action, snarky dialog, and just enough steamy romance to make it well-rounded story. If you’re a fan of the Alex Craft series by Kalayna Price, or the Mercy Thomson series, by Patricia Briggs, you’ll love BORROWED SOULS. I can’t wait for the next installment!”
