This story is so cute :)
There's not much to it and it's fairly predictable but it's a perfect comfort read. Very sweet characters and fun premise. It got pretty emotional and addressed big things that college freshman face so it's perfect for that age, but I think any age could connect to it (maybe pg-13 though). It's not super well written, and some of the descriptions were kind of weird. We didn't delve into the physics much if at all, even though it was a major focus of the plot. But the characters felt super real and the emotions were well expressed. I'll definitely look into more by this author when I need a quick easy read. 

Not about the book, but the blurb is a little misleading and for the first bit of the book I thought that she'd be in the time loop with Lucie (how is Miles an archnemesis if she's known him for one day?)
