Kara Danvers and Barry Allen. Supergirl and The Flash. Girlfriend and boyfriend. After several months of dating, these two superheroes are finally starting to get serious. But then Kara's life becomes unexpectedly more complicated with the arrival of a Kryptonian she never knew existed. He looks more than a little bit like her famous cousin...except he's younger. And he's shockingly violent - perhaps too much for either her or Barry to handle. Who is this Superboy, and why is he here? (Follow-up to the Spidey & Speedy Trilogy.
