Help with a (query) replacement

[Ypo]

Hi

I am copy-pasting e-books into org-mode to read and study them.

Usually, words come hyphenated, like "ato- mized", that I wanted to transform into "atomized".

I am trying with query replace, but I am starting to think that it is not the correct tool for this job.
I tried "query-replace [a-z]-" but I don't know how to exclude the letter before the "-".

What would you advise?

Best regards
