Lost in Las Vegas

I finished the fifth book in the Carter House Girls series, Lost in Las Vegas, by Melody Carlson. It was a book that taught me more about the main characters, but was not exactly a fast-paced or action-filled book. It was mainly centered on the unreadable Taylor. She invites DJ to spend Christmas with her, and DJ, lonely with all of the other girls gone, agrees. She is nervous however; Taylor apparently has big party plans-and Taylor's parties involve drinking. When DJ arrives, she discovers her worries were real. Taylor, behind her singer mom's back, is sneaking into bars underage with a fake id. She drags reluctant DJ with her into one, but DJ excuses herself and returns to the hotel, waking up to find Taylor with a hangover. This same scene repeats itself over and over again, until DJ wearily tells Taylor's mother the truth about her daughter's drinking habits. Taylor reveals the reasons as well- and they explain many things in Taylor's complicated moods, actions, and life. Taylor signs up for rehab, but leaves on her own to fly over to the clinic, but DJ is worried. Did Taylor actually go to the clinic? There is no way of knowing for now...
