Yume - Samuel Todd

To rescue a child of the dreamworld, a rebuilt Thomas Garner is forced to confront a truth more devastating than anything he faced before: some doors, once opened, cannot be closed without sacrifice.
Yume was never meant to exist. Born within the shifting boundaries of a world between sleep and waking, she is both miracle and anomaly-a living echo of a love that should have ended.
As the government tightens its grip and One's menace grows, Thomas begins to realize that rescuing the girl while fighting to change his wife's fate may cost him everything he has left.

In this second installment of the Sleepyhead series, science further gives way to faith, which is tested in the face of unbearable loss. One man must decide whether salvation means victory or surrender.
Yume is a story of grief, redemption, and the fragile hope that survives when the impossible becomes real.
