This book takes place 5 years after the first book ended.
Aubrey has graduated her online college classes at Gotham University, and has started her career as a history teacher and Gotham High School. Dick is a newly promoted detective with the GCPD. (Gotham City Police Department)

⚠️Spoiler⚠️ If you have not watched all of Young Justice do not read beyond this point.

For the sake of my timeline for this Wally never dies and Conner never went to the phantom zone.
