Supergirl has learned that the destruction of Krypton may not have been the accident always presumed. In fact it may have been deliberate, and a conspiracy. Killers of Krypton saw her following clues and told she’ll have to search for a set of memory crystals revealing the truth, and she acquired an ally along the way.

Marc Andreyko doesn’t make readers wait long before revealing what many might have expected, that her new Coluan friend is more than a little conflicted. By then, though, Supergirl has been captured, she’s without her powers and the Omega Men are heading her way for a team-up. Having Supergirl search for the crystals scattered across the galaxy is a method of dragging her from place to place, but as with the revelation, Andreyko doesn’t continue the obvious too long. He’s been showing the villain of the piece throughout Supergirl’s journey, and their presence becomes greater the closer to them she gets.

The pencilling is shared between Kevin Maguire and Eduardo Pansica who have mutually compatible styles, both clean, with Maguire more likely to go for viewpoints closer in and to play with expressions. When it comes to action both serve up what’s needed, although Pansica is more attuned to the all-out spectacular.

75% of Sins of the Circle is fun, with Supergirl bopping about the place and getting ever nearer to the end of her search, with the axe of Rogol Zaar proving both gift and curse. However, over the final few chapters Supergirl’s story comes crashing up against events of Superman’s title, and while she remains in focus, she’s sharing it with others, and Superman’s story intrudes. In the end it intrudes too far and there’s no great clarity to what’s happening without consulting Superman: House of El, and that’s unsatisfactory. The end has Supergirl back on Earth with the villains having paid a price, setting her up for Infectious.
