Abigail’s second year at the Tarkana Academy has been an all-out disaster. She’s just unwittingly helped Vertulious, an ancient he-witch and powerful alchemist, destroy Odin’s Stone and restore his powers, and now all of Orkney is caught up in the threat of war as the witches prepare to destroy the helpless Orkadians. Determined to set things right, Abigail and Hugo set off for Jotunheim, the land of the giants, to find a weapon to restore the balance. All they have to do is track down the God of Thunder and convince Thor to turn his hammer over to them.

When their former-friend-now-foe Robert Barconian arrives with a band of dwarves, intent on stopping them, Abigail and friends must unite to prevent a war that will destroy them all. But has Abigail made the biggest mistake of all by trusting in the wrong ally? 

So far this is my favorite book of the series. While Abigail, Hugo, Endera and others are still children, their emotional depth has grown as is really evident in this story. Abigail especially is struggling with the weight of what her decisions and actions have contributed to and suffers from a lot of personal guilt – while Hugo is steadfast in helping her and being her lifeline. Once again they go on an exciting adventure in order to set things right, which tests the bonds they have with each other and others. We see some familiar characters, but also some new ones along with way, as well as more figures from Norse Mythology which I thought was a nice touch. As with the other books in the series the book was fast paced and a fun read.

Happy reading!
