I've been kidnapped by a caveman. I came to Russia to find my missing father. He disappeared when I was ten and I haven't heard from him since. But I've barely stepped foot in Russia when a feral caveman rips me away from my campsite in the middle of the night. Maxim is a Mafia Don who hunts his family's enemies in a cave. He hasn't been around a younger man in ten long years, and when he brings me back to his dwelling, he offers me a deal I can't refuse—three months as his live-in cave husband and I can go free. I should scream and try to fight him. But when Maxim puts his mammoth palms on my tight virgin body and orders me to call him Caveman Daddy... There's not a damn thing that will make me leave. Caveman Daddy is a full-length MM Mafia Daddy romance with an age gap, lots of spanking, a Siberian tiger who likes cuddles, and a super-sweet HEA! This is the FINAL book in the Russian Protectors series before Aster's new series begins March 18! WARNING: EXTRA STEAMY!!
