My Promise by Noah Bolinder

Rating:  ⭐⭐⭐⭐
This story left me feeling sad. I got all the cryptic clues as my spiritual faith runs very deep in me, and I'm a very good mystery solver.  I cried for Grace as she realizes who the "The Professor" is. This story is very well written and drew me in. I became confused during the climax of the story, because I can't decide if she went home or she is still at the college. I actually felt a little letdown, because the epilogue is in another book. It makes the story seem as if it can't stand on its own.
