I've never heard of that, Suzie. I'm going to have to check it out. I'm always look for new books to read. <3 Even though I already have 22 on my yet-to-read book shelf. Lol.
Everyone loves Harry Potter :3 And mine is either (im so indecisive) The House Of Night books by P.c. and kristen cast or The Morganville Vampires by Rachel Caine. :)
Younger - Chronicles of Narnia. Older - anything by Minette Walters or John Wyndham (not really series but themed). I also collected every single Agatha Christie!
