Here's a summary from the cover copy:
"A hysterical phone call from Henry Archer's ex-wife and a familiar face in a photograph upend his well-ordered life and bring him back into contact with the child he adored, a short-term stepdaughter from a misbegotten marriage long ago. Henry is a lawyer, an old-fashioned man, gay, successful, lonely. Thalia is now 28, an actress-hopeful, estranged from her newly widowed crackpot mother -- Denise, Henry's ex. Hoping it will lead to better things for her career, Thalia agrees to pose as the girlfriend of a former child star and current horror-movie luminary who is down on his romantic luck. When Thalia and her complicated social life move into the basement of Henry's Upper West Side townhouse, she finds a champion in her long-lost father, and he finds new life -- and maybe even new love -- in the commotion."
Yep, that sums up the book. I enjoyed it, although it was almost a bit slap-happy for me. I don't remember her other books being that way....although it fit with the whole showmanship aspects of Thalia and the "horror-movie luminary."
I had trouble remembering that Henry is the central character and that Thalia wasn't the main focus. If I had, I would've been more content in her story being more of a periphery one.
