This review might contain spoilers as it is book 2 in the duology.
I listened to the first book in the series, The Scorpion Rules, in audio and intended to pick up The Swan Riders in audio format too. The first book dragged a lot in the beginning, and I briefly considered reading the sequel in paper as I felt I could skip over boring parts. I checked out The Swan Riders from the library. I tried reading it but it was even less exciting, so I switched back to an audiobook.
I had a lot of reservations before starting The Swan Riders, but I wanted to finish the story, so I persevered.
