Help me people

Ok so I read (and can't remember the name of) a motorcycle romance novel .. I think it was via my amazon kindle account but i can't find it on there, anyway!

The book is part of a series, and the initial book is based on a member of the mc saving a woman in the forest from being killed by a serial killer, he then brings her back to the clubhouse, but she wakes up with amnesia! They end up falling in love while she has no memories, but her memory comes back and it turns out she's a cop tracking the serial killer! She quits being a cop but sticks with her mc biker dude and they go about saving women.

The second book describes how the mc now save women from dangerous situations, and the book tells the story of one member falling in love with a high priced escort/call girl called "Lilly"
