The Hand of Raziel - Daughter of Mars, #1

Risa Black will decide the fate of an entire planet. After all, an angel told her so. Orphaned young, she grows up among the resistance, fighting to give the people of Mars command of their own destiny. Two governments from Earth vie for control of the Red Planet. She wants them gone, regardless of how many explosives it takes. To the outside world, she's an emotionless, broken marionette. Inside, her father's fiery end haunts her every waking moment.
She never cared for destiny or politics, until the angel Raziel focused her anger. Both friend and foe alike believe her grip on sanity tenuous, but she knows he is real, and pities those who will never feel his divine presence. Whenever her adrenaline wears off, guilt at what her bombs did cuts deep, as does the apathy of the citizens she fights to liberate. The pain worsens after unexpected love cracks open her armored heart, causing her to question the role she plays in the bloody conflict.
Torn between duty and desire, she learns change never comes without loss. Even to the Hand of Raziel.
