Or was it all a dream? And who is Nicola?
This book ends on a real cliffhanger and I cannot wait to read the next book in the series! IT did annoy me that practically nothing was abrieviated - it was all did not (not didn't), is not (not isn't), etc. -and  the passionate parts were kind of gross, but the plot and suspense made up for it. I would definately roccemd it, but only to 16 +, or at least in 10th or 11th grade.
I would rate it a 4.7/5
