Buried

NO, BIG NO.
I felt weird right from the beginning with characters appearing in sequences badly written you'd think you're watching a made-for-TV movie. It's as if the author was just pointing out what characters A, B, etc. were doing instead of telling a story.
If this is the way the author writes a suspense, she really should stick to romances.

Compelling characters, but lots of loose ends

The chatacters and setting are great. They are easy to love or love to hate. Some of the revelations were pretty obvious early on. But in the end you have to read all 3 for a satisfying ending. Maybe I will get around to the other two sometime.
