Query: Shadows of Mystery

I enjoyed reading this mystery/suspense love story novel. It was well written and easy to follow. I liked the intertwined parrell lives of the characters. I was intrigued by the twists and turns in the story. Daniel was an interesting character and as the story evolved it kept your riveted with the mystery behind the writer Julian Carax. Fermin was an interesting character that proved his loyalty to his benefactors. I got to dislike the villian Inspector Fumero in his role. The love story of Julian and Penelope and Daniel and Beatriz were similiar separated by years. The novel had humor, murder/mystery/suspense and love. I would recommend this novel to my friends.
