Faerie Marked by Brea Viragh

No one said escaping her bloodthirsty fated mate would be easy.
Half Fae half wolf-shifter Tavi Alderidge’s only chance to dodge a dangerous and disturbing arranged marriage is to attend the Fae Academy for Halflings. There’s just one problem: shifters aren’t allowed.
Her hope comes in the form of a potion to suppress her shifter half while she works to earn her ticket to Faerie, the cost steep but one she’s willing to pay for a chance to escape. However, surviving the Academy’s cullings meant to weed out the weaker students isn’t all it’s cracked up to be when a murderer begins taking out the top students.
Soon, Tavi finds herself doing the one thing she swore she would never do: falling for another student. And when she discovers he’s the Crown Prince of Faerie, she realizes the one person she thought she could trust is the last person who can ever learn her secret.
