Okay, this is book one of the Withern Rise series.
I had hoped to give this a good review, but I had these books (the entire series) as physical books, which mean that I wasn't able to easily quote parts of the book, and include said quotes here. So, you get a (admittedly drunk) review instead.
I enjoyed this book enough to read all three books of the series. In this book, we have Alaric, whose mother has died. He accidentally falls into another timeline where his mother hasn't died, but he actually wasn't born, Naia was. Alaric, of course, wants his mother back, and, well, quite honestly, who wouldn't want his mother back?
The story becomes about Alaric and Naia and who gets to keep the mom.
It's a good book, and having read all the books in the series, a good series, aimed at the young adult level of reading. I enjoyed them, but have no quotes to post, because, well, I lost all the pictures of the parts that were quote worthy. Ooops.
