Besides the story line of the abductions, there is also a bit of Super Girl's backstory. She shares with the Kents some events that happened back on Krypton before she was sent to Earth. It seems that there were bullies on her home planet, just as there are here in our solar system. She also has test anxiety, which is something that many readers can identify with. And the final showdown with the mysterious kidnapper shows what the students have learned in a very hands-on way.
It is fun to see the characters as teens still perfecting their skills and growing into their powers. The fact that some of them eventually become villains in their adult lives makes it very interesting to see them all as friends in these stories. Overall, the combination of favorite characters, a school setting, their interactions in that setting, and the mystery of the kidnappings combine to make an entertaining story and leave plenty of room for future adventures. Fans of shows like "Teen Titans" will find the same vibe.
I read an e-book provided by the publisher through NetGalley.
