City of Crows, book 1 : Soul BreakerClara Coulson2015

Two years ago, Cal Kinsey was an up-and-coming cop in the Aurora Police Department. But during a fateful nighttime stakeout in search of a prolific killer, Cal witnessed the darkest corner of his dreams come to life. A rogue vampire slaughtered his partner — to put it nicely — and introduced Cal to the supernatural world he never knew existed in the shadows.

Now, Cal is a newly minted detective at the often mocked Department of Supernatural Investigations. By day, the agents of DSI are called “Kooks” by local law enforcement. By night, they’re known as “Crows,” reviled by the supernatural underworld.

Mere weeks out of the academy, Cal catches his first real case, a vicious murder at a local college. An unknown sorcerer has summoned a powerful creature from the Eververse, a realm of magic and mayhem that borders Earth, and set it on a dangerous warpath through the city.

Between butting heads with his grumpy team captain, stirring up ill will with the local wizards and witches, and repeatedly getting the crap beaten out of himself, Cal must find a way to stop the Eververse monster and send it back to the hell it came from…

…preferably before Aurora, Michigan runs out of coffins for the dead.
