I read this novel free and early, thanks to Net Galley and St. Martin’s Press. It’s for sale now.

Shay Miller has watched a woman die, and now life will never be the same. She is alone in the big city, barely getting by like so many working class women. She is in love with her roommate but doesn’t rock the boat by propositioning him; she has no friends or family nearby. Then one terrible day, she is waiting for her subway when a sinister looking man turns in her direction. Imagine how glad she is to see Amanda, a normal-looking woman who’s also headed her way. But instead of providing the security Shay is hoping for, Amanda jumps onto the tracks in front of a moving train.

It happens so quickly!

Shay is the sort of person that relies on information to deal with stress. She has a little notebook, what she calls her “Data Book,” filled with all sorts of oddball statistics that she quotes from at the start of each chapter and throughout the novel. (Frankly, I could have lived without this feature, which began to feel like filler at times.) She deals with the stress of having witnessed a suicide by finding out every single detail she can about the late Amanda.

And this part is the hardest aspect for me to buy into. She’s haunted by what she saw; okay. Amanda looked a lot like Shay, which made her more fascinating to our protagonist. Fine. But the obsessive way she pursues information—even once she finds she has the dead woman’s necklace, which she had forgotten momentarily—doesn’t jibe with me. She goes to her apartment, visits the woman’s mom…huh. Go figure.

Now, once I quit rolling my eyes and allowed myself to buy this premise, things flowed a lot more smoothly. Cassandra and Jane, friends of Amanda’s, hold a memorial service for her, and it is by attending this event that Shay comes to know these two sisters. They are kind, they are solicitous, and they are caring. Before Shay knows it, they are her new best friends, and because she herself is a good person—if a little odd—it doesn’t occur to her that their motives might not be as benevolent as they pretend to be. They are the spiders, and she is the fly.

Here’s the thing I like best about this story. Shay’s character has to be rock solid for it to work, and once we get past the stupid parts at the beginning, it is. I half expected her to be dumb as a box of rocks all the way through, but not so much. The way she is developed, neither too unrealistically savvy nor ultra-naïve, is admirable. There’s a thin path through the middle between these two extremes, and I wondered if she would be the dithering idiot that has to be saved by someone smarter, but that’s not how it shakes out. There are a couple of loose threads that are left dangling, but it’s the way Shay’s character is crafted that wins the day.

Those that enjoyed this authorial pair’s other books will like this one too; those in search of a good beach read or a fun weekend book should consider this one. All told, big fun, and delightfully original.
