The Iron Queen (Daughters of Zeus)

Life is hell for Persephone.
Zeus will stop at nothing to gain access to the living realm and the
Underworld, and as the only living god with a right to both, Persephone’s in
trouble. Captured and tortured beyond the limits of her resolve, Persephone
must find the power to stand against Zeus. But will she be strong enough? 

Meanwhile, Hades contemplates
desperate measures to rescue his queen. Persephone never thought of herself as
dangerous, but there’s a reason gods never marry for love. A being with the
power to destroy all of creation shouldn’t place more value in one individual
than the rest of the planet. But Hades...Hades would break the world for her.

 To save the world and
stop both Hades and Zeus, Persephone must make a difficult choice. One that may
cost her everything.
