This is the second book in the KEEPER'S CHRONICLES series and picks up shortly after SUMMON THE KEEPER ends. Claire, a young Keeper is still undecided about her romance - or lack thereof - with even younger Bystander Dean. Her cat, Austin, is always ready to offer her advice as is her bratty younger sister, Diana. To make life even more frustrating the family business of keeping good and evil in balance is particularly busy at the moment due to the holiday rush.
The trouble seems to begin in a traditional source of torment - a high school - and leads to a scene between an irate father finding a naked teenage boy in his daughter's bedroom. The daughter's explanation, that this is not a boy but an angelic manifestation, does not calm dad down.
Like SUMMON THE KEEPER, THE SECOND SUMMONING is set in modern Canada, and involves a family that is part of a group who keep the world balanced between good and evil. The tone of this series is hilarious, particularly for anyone who has ever lived with a cat.
If you are into serious scifi/fantasy (Anne Rice for example) you probably won't like this but if your tastes run more towards life's absurdies this is for you. I would recommend starting with SUMMON THE KEEPER though.
