This book contains 9 pages of wonderful extras for you magic users in Pathfinder. It is published by Super Genius games and I would say it is heartily worth a read!
With loads of extras for mages (including the ability to get a genie companion) there is plenty to build up on from the Latest paizo book Ultimate Magic. There are new abilities and a two new wizard power sets as well.
Loads of tasty extras to get boost up your spells, loads of information and none of it feel particularly overpowering from a game balance setting.
