Eye of Dominion by David Staniforth

This is the sequel to Alloria, the tale of Alloria finding out she is the first wizard's daughter.  They think they have vanquished the villain in the first book, but it seems his spirit is still alive.  Alloria has join her father Ymarid, and their protectors Bane and Nathan and venture back into the labyrinths to visit other worlds to save their world.

This story is about Yrion, Alloria's brother who is jealous that she has returned.  Yrion is under the influence of Glebester, one of the most gross characters I've ever read.  I really disliked reading about his "seepages" to say the least.  His hold over Yrion was very powerful

I enjoyed this story, even though its intended audience is the teen YA market.  It had enough grown up intelligence without talking down to the younger audience.
