I have read the Twilight series so many times that I can probably almost quote the thing. But I loved the romance and the adventure and I haven't been able to find anything comparable to it... until now.
My mum recently lent me a book called "The Hour Glass Door" by Lisa Mangum.
It hasn't got any vampires in it, but it has got characters that are believable, an intriguing love story and an original plot. I really enjoyed it immensely and if you liked Edward, I have a feeling you will find yourself easily attached to Dante.
I am warning you ahead of time, the next book doesn't come out until the Summer of 2010, but I don't think you will regret reading it one bit. It's an easy read, and if you're like me, you won't want to put it down. :)
