One Last Book from the Box and Jack Is Back

Recon Academy: Mixed Signals by Chris Everheart (978-1-4342-1915-2)
Tolerable. I can't figure out what motivates the bad guy, or why the main characters all run around in jumpsuits, however. There was unintentional humor in the use of the phrase "After them, you fools!" on page 53--so cliche I couldn't believe it was being used. The technology aspect was interesting. (I know, no real plot summary, but I can't find the energy).

Calamity Jack by Shannon and Dean Hale (978-1-59990-076-6)
From the pages of Rapunzel's Revenge come the story of Jack, as he and Rapunzel head to the city to make up for some of his past mistakes. He's looking to see his mother again, and discovers things have gone from bad to worse in the time he's been gone. A giant has conned his way into control of the city--the same giant Jack tried to rob some time ago. It was that botched theft that sent him on the run to the West. Rapunzel's influence has caused a desire to reform in Jack, and now he has to make good on his promises... YES!
