Reviewing Marx Returns in the Los Angeles Review of Books, Nina Power described it as "an imaginative, uplifting, and sometimes disturbing alternative history". Writing for The Australian, Peter Beilharz declared that "The story that Barker tells is incredibly witty, clever, and creative. It is amusing and entertaining as well as instructive."
Barker discussed his novel at the British Library’s Karl Marx bicentennial event on 5 May 2018. Other invited speakers were Clive Coleman and Richard Bean, writers of the 2017 West End play Young Marx, along with "the team behind Raoul Peck’s film The Young Karl Marx". The event was moderated by Eleanor Marx biographer Rachel Holmes.
