Dactyl Hill Squad

It's 1863, and dinosaurs roam the streets of New York as the Civil War rages between raptor-mounted armies down South. Magdalys Roca and her friends from the Colored Orphan Asylum are on a field trip when the Draft Riots break out, and a number of their fellow orphans are kidnapped by an evil magistrate, Richard Riker. Magdalys and her friends flee to Brooklyn and settle in the Dactyl Hill neighborhood. Together with the Vigilance Committee, they train to fly on dactylback, discover new friends and amazing dinosaurs, and plot to take down Riker.    

Magdalys and the squad are flying south on pteroback. South to rescue her older brother. South to war. The squad links up with the dino-mounted troops of the Louisiana Native Guard, an all-black regiment in the Union Army fighting to free their people. They're led by General Sheridan, surrounded by enemy forces in Tennessee and desperate for any edge to sway the tide of battle.
