I love the study series, I really do, but five books in, not only am I questioning how often the characters get captured, but so are they! It's starting to get a bit repetitive in that respect. The Yelena/Valek scenes still get me right in the feels though and I really enjoyed the minor arc where Valek's past catches up to him and the ensuing plot twist that results. 
 This feels very much like a "second of a trilogy" book - it's building to something huge and almost epic in the third, setting up some very high expectations. I'm desperately hoping Snyder can pull off what's needed for the scope of the conflict and still resolve everything in a satisfying way. 
 As much as I love the characters and the world in the Study and Glass series, I would love to see Snyder turn her talents to something new after she finishes Dawn Study.
