In Tanya Huff's delightful new follow-up to her acclaimed Locus bestsellers, Summon the Keeper and The Second Summoning, a force from the Otherside threatens to break through to our world and destroy the balance between Light and Darkness. Unless, of course, the Keepers Claire and Diana-two sisters who are able to reweave the possibilities of time and space-can prevent a permanent rift between worlds...at the local shopping mall.
