Unconditional of the work of Carlos Ruiz Zafón, I plan to visit the places described in his works; where the purchase of this little book. Admittedly, I found a lot of information, but presented little practical way to read; the map of Barcelona, for example, is unusable, or almost! And references to works juxtaposed with personal comments of the authors, are sometimes difficult to define. But no doubt: I will go to Barcelona in the footsteps of the heroes of Zafon's novels, and I will have this guide in my pocket!
