This book is the sequel to The Wrath and the Dawn, and the final book in the duology.
I wasn't impressed. To be honest, after re-reading the first book, I had more sympathy for Tariq. In the second book, that sympathy grew--but then it was coupled with irritation.
The Rose and the Dagger is a good book, and those who loved The Wrath and the Dawn will be happy with its sequel--the books just weren't for me. Check it out!
