Brightstorm

The Brightstorm twins have learned that their father, a famous explorer has died on his most recent trip. They have lost everything. Even though they are grieving, they can't help but feel there is something missing from the story of their father's death. They have no choice but to go on an adventure of their own to find the truth.
I loved this book! Such an amazing story. These characters are fantastic. I will definitely continue the series. This is a new favorite middle grade for me.
