3.5 Stars, rounded up.
The Lost Story is an enjoyable fairytale retelling (extention?) with an interesting premise. What happens after?... After leaving Neverland, Wonderland, Narnia, or Shanandoah?
However, this did feel a lot like two separate books at times. We start the story, mainly following Emilie and the pursuit of finding her sister in our mundane world. Which leads us to 2 lost boys, Jeremy and Rafe. Naturally, Emilie's missing sister has ties to these lost boys. Add in some memory loss and cryptic suggestions from Jeremy and our MCs are off to Never-never Land! And from there we get a lot less Emilie and really dive into J & Rs history.
I preferred the more fantastical parts of the story and yet somehow the relationships still felt rushed, since a lot of history was packed into the last third of the story. Overall, the Lost Story had plenty of heart and I'd reccomend it to anyone who enjoys fairytales.
