Drink Me at Fang O'Clock — Marian Tee

Four powerful vampire brothers. Four human wards. And in this steamy and fast-paced paranormal age gap romance... Drinking the blood of an untouched is what makes creatures like Gaël powerful...and it's the perfect excuse for Juliette, who hasn't the courage to tell her vampire guardian she's in love with him. Gäel has always thought of Juliette as an obedient child, so he's stunned when his suddenly-rebellious ward insists it's her duty to surrender her innocence to his possession.  He has always been chained to his past, but having his ward in his arms changes everything. And just when Juliette has begun to believe there's a chance for them...that's when she finds out her blood might be her guardian's downfall.
