I couldn't keep all the plot threads straight on this one. Everyone was so inter-connected and the names and identities started to get so convoluted, I felt like I should make a chart to keep everyone straight - Robin and Renee and Nikki, but also Summer and Quentin and Rex and Jenny and april and Gabriel and Elizabeth and Karen and Eric, and wait, wasn't there another girl named Kimmy? My head was spinning by the end and nothing seemed to make a lot of sense from a psychological standpoint even though it did make the plot twisty-turny. It's well - written but for me, too many people (actually basically all the characters) aren't who they seem and there are so many coincidences, it spoiled my enjoyment. I give a writer one big coincidence, usually at the beginning to set the plot in motion - after that, I want events to follow logically.
