I think you did an amazing job writing this book- I learned a lot about sledding and arctic temperatures from your story. The research you've done really shines through elevating this book from being potentially good to really great. I haven't read a YA that I enjoyed as much as this one in a long time and I think the fast-paced adventure coupled with high stakes made this a win for me (and my love of dogs). I also enjoyed that there was very little to no romance- this novel stood solidly without that added element and I liked that you focused more on Sena's bond with Iska instead!
Such a great book!
