Rating this book honestly, it probably should have been two stars. The characters are flat and very one-dimensional (Abra does housework because she thinks it's fun... first, that's a gender stereotype, and second, does anyone really do that sort of thing for fun?). The plot is stereotypical and piled high with tropes (sweet, female lead heals the troubled male lead; they fall in love; Grandma is trying to set them up because Eli "needs a woman in his life," etc.). The romance is forced in the beginning - Abra pushes herself on Eli every chance she gets (which would be construed as rape the other way around) - instead of telling this annoying, nosy neighbor to leave, they fall in love. What? Of course, Abra has a stalker, like every female mystery novel lead does. The ending is cheesy at best. The novel is very formulaic and doesn't add anything new to the genre. 
 But, that aside, somewhere in the last quarter of the book, I realized I was a little sad it was ending. (view spoiler)[Eli proposing with the mystery treasure gem was sweet, even if it was cliche. (hide spoiler)] Though one-dimensional, I could see semblances of real people in the characters by the end. I liked the historical bits and the search for treasure - it had a modern-day pirate vibe to it, and I love pirate novels. So, for the small emotional response it elicited, I'll bump this one up to three stars.
