Mr. October by Nicole S. Goodin

Masen Lennox.
Music superstar.
Recovering alcoholic.
… And in need of a fake girlfriend.
Billie Tatum.
Sweet as sugar.
Unexpectedly sexy.
… And under his skin.
Masen’s reputation as music’s bad boy finds him on the verge of losing his entire career, and the best way to clean up his act is to get a woman on his arm.
Billie has no idea what she’s in for when she agrees to play the part of Masen’s girlfriend, but as lines between real and fake start to blur, she’s about to find out.
Masen doesn’t believe in love.
Billie can’t help but hold onto hope.
The last thing Masen wants to do is break Billie’s heart, will he put aside his past and let her in? Or will she only get to keep playing pretend?
