This book "Wet Linda" is the first novel by Paul Paducci - and on this showing there's a promising future ahead for him.
The story tells of a body-conscious teen girl who moves,with her family to a new home in California. She doesn't fit in with the local "pool-crowd" so goes to the local community pool where she comes under the influence of an evil water demon (the eponymous Wet Linda) who uses her to wreak her vengeance.
It is a very well told story which is not afraid to be graphic in it's nastiness. It had me holding my breath at times, proper edge of the seat stuff.
If you like your horror gritty, this one is worth a go so try it out.
And no vampires or zombies - another plus point.
