"If you haven't read Big Jack, get it first"
Although the In Death numbering scheme makes it look as if this book is the sequel to Imitation in Death, it's not. Between the two, Roberts wrote a half Roberts/half Robb novel called Remember When, a two part book set half in present day and half in 2050s NYC. Only the second half is about Dallas, and it's available standalone under the title Big Jack. It's a very nice story, so go back and get it if you missed it.
Now, about this book...
I'm listening to the series in order, and Divided is my favorite since Witness. There is real tension between Eve and Roarke as he is torn between his desire to protect her "bad Roarke" style and his respect for the law through her.
There is, as a negative review noted, a higher percentage of dialog to action than in some other books, but if you're into series fiction it's really all about the characters. This book has some great Roarke and Dallas character development, funny and touching scenes with the still pregnant Mavis, and some interesting glimpses into the workings of the mysterious Roarke Enterprises.
