If you are looking for like a romantic suspense novel (i kno, i kno)... but it is REALLY good. Get Jeams Patterson's 'Suzanne's Diary for Nicholas'.
It is so suspensful... and soooo sad.
Patterson usually writes mystery thrillers so thats why i picked it up, but even though i was dissapointed to find it be a romance, it was worth the money. Really good read. Not very light at times though.
