Life of the Party by C. Erin Anderson

Trigger Warning: This book contains mature themes and descriptions that may be disturbing to some readers. Reader discretion is advised.

Seventeen-year-old Mackenzie Taylor can’t wait to be free from high school, to leave behind her disapproving parents and finally escape the shadow of her perfect older sister. The rebellious party girl has a perfect accomplice in best friend Riley, a boy from the wrong side of the tracks who scores them drugs, booze, and underage entry into the best club in town.
Until that one fateful night changes everything.
Shaken to his core, Riley abandons their wild lifestyle, just as Mackenzie meets Grey Lewis, a broodingly talented, aspiring musician whose gorgeous body and ample drug supply are too tempting for her to resist, no matter how much Riley warns her to stay away.
Previously inseparable, Riley and Mackenzie go their separate ways.
When summer hits, Mackenzie has new friends, a new apartment, and new drugs to mask the pain of Riley’s absence. And, of course, she has Grey. Despite the fierce, consuming passion they share, the mysterious crooner always leaves her guessing. Is Grey really a good guy? Or was Riley right about him all along?
Mackenzie’s in too deep to care. Unable to curb her mounting addictions, before long, she’s totally lost control. She forgets Riley, forgets her family, forgets everything but Grey and their next hit.

Fortunately for Mackenzie…Riley has never forgotten her.
