Fairy Tail Volume 15 by Hiro Mashima
The Battle of Fairy Tail continues as Laxus' small cadre of wizards, the Thunder Legion, has been defeated. He has to enter the fray himself, though few of the Fairy Tail wizards are left. Heavy hitters Natsu, Erza, Mystogan, and Gajeel are still up for more fighting. They have to contend with Laxus's lightening magic and his Thunder Palace--a set of 300 small orb encircling the town of Magnolia which threaten to release an electricity attack on the town if the Fairy Tail people can't stop them in time.
The fights are exciting and they have a lot of kung fu-type sparring along with the magical strikes. I am impressed that the battles get more and more epic as the story goes along. You'd think a limit would eventually be hit but Mashima manages to squeeze out more as he goes. He puts in a little character development and some new mysteries as well, so there's plenty to enjoy.
The book includes a side story, "Natsu and the Dragon's Egg," which is very similar to one of the filler episodes on the anime series. The other typical supplements are provided.
