From New York Times best-selling author Mackenzi Lee, Gamora and Nebula:
Sisters in Arms follows Gamora and her sister Nebula as they play a cat
and mouse game with galactic consquences--and each other.
Gamora doesn't know who sent her to the planet Torndune. But as the
reliable right-hand daughter of Thanos and one of the galaxy's most
legendary warriors, her job isn't to ask questions. What Gamora doesn't
know is that her estranged sister, Nebula, has chased to Torndune, eager
for revenge.
Soon the two sisters make unlikely alliances and find themselves in a
twisted competition with galactic consequences. It's a game they're
destined to lose--unless they learn to trust each other. But trust is
the biggest lie in the galaxy ...
