Review by Ian Keogh

Corollary is based on a very simple, but oh so effective idea on Adam Rose’s part supplied with the opening caption. There’s a universe where everyone has a twin, and if your twin dies, so do you. However, every rule has an exception, and in this case it’s Andromeda, who survived the death of her twin, and plenty of people are keen to test her in an effort to figure out how. Some would be more intrusive than others.

Andromeda figures out much on the hop, taking on missions between bouts of cryo-sleep, and a fast-moving opening chapter pretty well lays out who she is and supplies a likeable character. Robert Ahmad draws the action very loosely, filling in much of the depth with effectively chosen muted watercolours. It’s a simple, adaptable style that’s quite old-fashioned, yet reassuringly so, with strong storytelling making everything clear.

However, as far as Andromeda’s current mission goes it isn’t clear. She’s been holding something back, and there’s a surprise to end the opening chapter. It relies on a clever misdirection, and shouldn’t be spoiled in a review. Further revelations drop to begin the second chapter, disclosing that Andromeda’s adventures have a greater purpose, and it should give readers a sense of outrage to match Andromeda’s.

Corollary appears aimed at a young adult audience, as it’s generally lighthearted despite some fairly heavy plot elements, although some injuries are shown a little too graphically. It would slot very easily among the content run in 2000AD Regened. Rose has enough imagination to keep funnelling in inventive touches, the foreshadowing is subtle and drops nicely into place, and while there was always going to be a happy ending there are plenty of twists before reaching it.
