Trap is part 2 in the trilogy which begins with Snare. I think it is best read as the second act in a three act drama.
It continues the story of Sonja and Agla well, building up to the third part, Cage – due out in October 2019. The blurb on Cage will no doubt describe it as the ‘explosive’ conclusion, they always do, and I hope it will live up to that billing.
I am not sure how well this book works as a stand-alone work, and not as part 2 of 3.
I gave Snare 8/10, so Trap gets the same. When I read Cage, I will give the series an overall rating.
