I must say, I enjoyed Reboot much more. It stood out more and I just loved the relationship between Wren and Callum. 
 The only part that stood out for me was Em's subterfuge, good plan and one that took major guts. And I guess how hectic her family sounds... 
 Other than that it was somewhat typical. The inevitable feelings that developed weren't shared by me, they felt a bit contrived. And some of the things that were done for said feelings didn't feel right, I mean in Red Queen we see how one should act after a betrayal, this is not even close to realistic.. But love triumphs? 
 After Reboot I still adore Tintera so I will be checking out the sequel.
