When Birds Collide (White Canary/Mockingbird - DC/Marvel)

Sara Lance aka the White Canary is a once dead well-trained assassin. After saving the world from the immortal tyrant Vandal Savage, along with her unlikely team of criminals and heroes, they have become Legends. Her life after that grandest adventure has been lacking somehow. She seeks to find her new place in life and fill that void she feels.

Barbara "Bobbi" Morse aka the Mockingbird was one of the best agents of S.H.I.E.L.D. She has been on the run since she and Hunter took the hit of being tagged as terrorists in order to save their team. Bobbi has encountered quite the number of strange things, but she wasn't prepared when she fell in a singularity that suddenly appeared out of nowhere. She knew other worlds existed, but another earth?

Their worlds collide as Bobbi explores this other earth and struggle to find a way back. Could Sara be the help she needs to find a way back home? And could Bobbi be what Sara needs to fill her thirst for another grand adventure?
