This was a fairly good read, but I found several editing errors. For instance, she leaves her purse in the hotel room, but when she needs a rental car, she pulls her drivers' license out of her back pocket. There were others... but I'm not going to nitpick. ( )

Pretty good start to a series about ex killer for hire whose past catches up to her. ( )

"Play Nice" is a quick and interesting read. Usually, 'suspense' stories are full of technical details. This one is not; perhaps the reason it does read quickly.
I must say, I didn't miss having as many details; the lack certainly can assist the reader's transition from disliking the heroine to feeling sympathetic, in relatively short time.
Also, outside of a portion of the story mid-way through, the plot and H/H were largely believable in their actions/thoughts.
I plan on reading the next installment of this new series, only having wished that I didn't know it was the first of a series when I did read it. Without that foreknowledge*, the last chapters of this book would have been wonderfully surprising, rather than happily satisfactory.
FYI: 1) *The reason I try hard not to include any story details in my reviews; and 2) This is the first book I've read written by Ms. Halliday.
I haven't decided whether I will read her previous books, as this story seems to have been a change in genre for her(?). Maybe, that decision will be easier after I've read the next installment. ( )
