Welcome to the Gambit and Rogue appreciation thread!
Rogue and Gambit ( 2018) by Kelly Thompson was a 5 issue miniseries by design. If you loved that and haven't read X-Men Gold (2018) #30 you definitely should. That then leads into Mr. & Mrs. X (2018-2019) which was really always probably going to be a 12 issue maxi series at most and is a must for most fans of these characters. All 2019 X-Men series were canceled by late summer according to long running plans to make way for Jonathan Hickman's take over of the X-books starting with 3 months of only two titles - House of X and Powers of X. Rogue and Gambit do not appear in these. They are now appearing in the Dawn of X relaunched Excalibur (2019) series by Tini Howard which came out late in October and is currently on issue 2. Thankfully Gambit and Rogue are still together, though if you read up this thread you will see fans are having some mixed feelings over their characterization and depiction so far. Also you might want to at least review the wiki summary for HoX/PoX before starting if you don't read those series because it established the new status quo for all X-books. The art at least is gorgeous and I do think they'll have some big developments coming in this book. Just hoping the writer gets a better feel for their voices and personalities at some point. But it's an ok story overall.
Whew, sorry that was wordy. Hope that answers your question?
