The dialogue in this book was magnificent. Witty, sparkling, unexpected and fun. It's worth it just for the dialogue. 
 There was a large crowd of additional characters included; family (dead and alive), fellow cast members, cast members of other plays, an ex-lover, the ex lover's new lover, theatre and household staff, neighbours... the neighbour's cat. They didn't weigh down the story too much, but some of it could have been sacrificed to the greater good - like giving over a bit more time to the almost non-existent sex scenes. 
 Richard, the dude - He's a prickly, arrogant fellow. But Lainie can cope with his sharp edges, she calls him out where he crosses the line and otherwise accepts him as he is. I like that. 
 Lainie is a red head - EXTRA POINTS FROM ME! I wish all female leads had red hair. I liked her a lot. 
 Do paparazzi and magazines bother to cover theatre actors? Seemed a bit strange to me, but it did help the plot and gave some interesting foreshadowing at the start of each chapter.
