This is another Blake & Mortimer album. Set in the 1950s, this is the second of a two part storyline combining political intrege, science fiction, and background on Professor Mortimer.
While published as the 10th volume, it's actually the 17th. It's the second album by the 'second team' doing albums after the death of B&M creator EP Jacobs. It's by Yves Sente & Andre Juillard. Cinebooks is publishing their 3 other albums this year (one more to go).
As noted, this is the second of a two part story. I advice getting them together. There are some things that follow from the previous album by this creative team, "the Voronov Plot", and I understand their other album, "The Gondwana Shrine", is a sort of follow-on to the storyline in this 2-parter. It will be published later this year.
In the first album, we learned some background information on Professor Mortimer, which impacts on the main story. Mortimer had met the individual who will be the main villian in this 2-parter, who blames Mortimer for the death of his daughter. We find out in this volume how that all really played out, and its full impact on the storyline. You'll need to read the albums to find out.
The main story is set in the 'present' of 1958 at the "worlds fair" in Brussels. A backdrop to this are the several nations (in the third world) who want to throw off the yoke of colonial domination. The main villian will use that as support for some new super-weapon, as well as making use of Col Orlik (released from prison as shown in the prior albums). Orlik is thus not the main villian, but another pawn. This album, the action soon shifts to Antarctica (the sixth continent of the title), as the resolution to the attacks on the "world's fair" is worked out.
Overall, a great story.
In the next volume, we find out what happens on Mortimer's vacation from the events of this story.
