Our view
Readers do not see the twist coming in “Secrets of the Dragon Sanctuary”, an intense, intricately plotted fourth “Fablehaven” adventure. Brandon Mull mixes magic and dragons with real tragedy, and the book leaves some of its readers shaken. Some readers feel the characters mostly serve the plot and stay thin as people. At 535 pages, it belongs to those already deep in the series.
