The Wayward Souls of Avalon

After the collapse of Earth sends the last of humanity soaring to Mars, documentarian Jocasta Thorne finds himself trapped in his spaceship on the outskirts of the planet's orbit. Nearly giving up hope of ever seeing another human again, Jocasta's quiet life is disrupted when a knock at the bay door breaks through the silence, and the stranger on the other side promises he can get them home.

The Wayward Souls of Avalon is a cozy sci-fi tale about two strangers caught in each other's orbits and their year-long trip to Mars, perfect for fans of Becky Chambers and "The Darkness Outside Us".
