Sanctum

More Mystery But Some Solid Action Too. This book is a short prequel of sorts to Woods's Crowley books - that alludes to far more possibility of prequels even earlier in the timeline. It is more mystery, with a lot of sneaking around finding clues, with the occasional grenade tossed or bone broken or trial by combat... but given its setting, it very much works. If you ever wanted to imagine what it would be like to unleash Jack Reacher into Hogwarts... this is your kind of book. ;) Very much recommended.
