Fans of Ian McEwan and Paula McLain will fall for this absorbing novel about love and madness, the toll of the First World War and family secrets, and an extraordinary woman's struggle to succeed in a man's world.

Imogen is going to hurt Quentin, and she can't bear it. He has been her only friend and confidant during her time at medical school in Chicago, but he wants more than friendship and she doesn't. Unlike most well-brought-up young women in 1916, Imogen does not want to be a wife - she wants to become one of the country's first female psychiatrists. And she has just accepted a residency at the world-leading Phipps Clinic in Baltimore that will take her away from her best friend and toward that future.

Quentin is shattered by her rejection and heads across the border to sign up with the Canadian Expeditionary Force; in one of his only cruel moments, he tells Imogen that he does not have the nerve to kill himself so he'll let the Germans do the job for him.

While Quentin encounters unthinkable horrors on the battlefields, Imogen faces her own struggles, whether it is the sexism that constrains her or the barbaric practices that are accepted as treatments and "cures" for the mentally ill. When she's told that Quentin has been killed in France, she falls into a bleak depression over what she has sacrificed to pursue her dream, which eventually leads her to a deeper empathy for her patients and even more passion to find real ways to help them.

Soon, her actions in pursuit of that goal put her on a collision course with the powers-that-be and lead her to a further reckoning with what Quentin means to her.

Into That Fire is an engrossing novel about a remarkable woman with a haunted past trying to carve out a winning future for herself. At its heart, it's a love story about uncovering one's true desires.
