Tomorrow Will Come

I'm awful at blurbs but yeah this is the last book of the Mary Grimes trilogy (Dont Look Back and Just Keep Walking)

Mary Grimes. She's seen it all; the worlds end, the loss of her home, battles, fights, her best friend and then brother's death. She'd lived through a war, a war that killed so many.
And now she's lost her father.
But even still, she's searching for hope. For a better tomorrow. She's an orphan, a war casualty, a broken child. But she's also a sister, a Doctor, a friend.
And she's desperate to show the rest of the world that tomorrow will come.
