(BTW THIS DESCRIPTION HAS A TON OF SPOILERS FOR THE WHOLE PLOT) Lila has taken over Marinette's life. Everyone in her class has turned on her, and Adrien has started believing Lila's lies. Marinette is ostracized, but Ladybug isn't. On Ladybug's solo patrol, she figures out who hawk-moth is, but instead of telling people she defeated him, she took the miraculous. At the same time, she was invited to Gotham to present her designs to Mr. Wayne. She uses Tixx and Nuroo to help build back her reputation but realizes that she doesn't need her old friends. She already has everyone she needs. (Also, I found the cover art on google and then kinda edited it.)
