    Feels incomplete... slight ranting
    Format: Kindle
    I liked the story. I liked the characters, they were easy to get to know and understand but this book definitely felt very “raised by wolves”. I made me really miss Bryn and it doesn’t feel finished. I’ve only read RBW and L&L by Jennifer, but both left me with a feel of the books being incomplete. I’m just left wanting more, and feeling slightly unsatisfied. I think her endings are a little rushed, I need a bit more closure. I want more answers. I don’t need everything wrapped up in a little bow, but if the author doesn’t plan on writing any more books then for the love of god please complete the ending and stop making the readers want more. Once again, a good book just frustrating.

    Not a Literary Review
    Format: Paperback
    I have not read this book in full yet. I bought it for my daughter. I'm not reviewing the literature, I'm reviewing the quality of the book itself. It's kind of garbage. The cover is cheap, the pages are beige and remind of the old manilla papers we used to buy for her kindergarten drawings. I was very disappointed in the quality of this book as it was purchased as a gift and it is NOT impressive at all.

    Such a well developed story.
    Format: Kindle
    I LOVE this book. She does such a good job of researching that you never question if she knows anything about search and rescue dogs. The characters were amazing(as usual). She rapped it up nicely BUT I’m really really hoping she makes a sequel. There’s just so much more I want to know/see happen with these characters after this.
