I read this with my five-year-old twins, who enjoyed the story and visuals. For me, this was not as good as the previous Super Hero Girls book we read together because the story suffers a bit from "whose story is this?" syndrome. Per the title and the cover, it should be about Jessica and her conflict around her confidence in becoming the new Green Lantern, but the story really centered around Supergirl and her history. Even the subplot involving Krypto was more Supergirl-focused. Jessica's conflict was resolved very quickly and became a nonissue in Supergirl's story. Overall, this was an okay volume, but not as focused as other entries in the series.
