HaBO: Spiderweb Tat on His Nether Regions

You did it! We figured this one out! It is a truth universally acknowledged (by me for certain) that the Bitchery pretty much knows everything, and really, it's true. Scroll down to see the solution for this HaBO - and many thanks!

This HaBO is from Rach, who is looking for a rockstar romance:

I’m searching for a book (series?) that came out post-2011. I read it in the hospital, deluded on Dilaudid, but even then I knew wtf-ery abounded.

The heroine is a moderately successful rock star (also a foster child from a troubled home, where she stabbed her abusive parents to death at age 16, a murder case that remains open) and lost her virginity the same week to an older rock guy who gave her the perfect evening while high as a kite, and left her knocked up & somehow immediately forgot about it? It’s several years later, but they have matching tattoos from that adventure.

Anyway, he’s forgotten she exists; she hates his guts. They run into each other on tour while he’s trying to hook up with her bandmate, an angry girl who holds the murder over our heroine’s head as blackmail material.

Hero pursues heroine for reasons. She admits she hates him because of their shared past and she tries to slice her tattoo off with a knife to make a point. There might be a kidnapping in here somewhere?

Anyway, they have a lot of foreplay in the form of angsty duets on stage and hot-but-interrupted sex scenes. They are by turns sweet and insane together. Unrelated to their shared tattoos, he had a spiderweb tat on his dick, which terrified me.

But how did it all end? I can’t remember and I want to re-read. Anyone?

Very few HaBOs render me speechless, but this is definitely one of them. It also took me a good twenty minutes to pick out which WTF piece of this to use as the title.
