Two novel-length YA steampunk adventures from the author of the wildly successful Murderbot Diaries.

Together in one volume for the first time:

Emilie and the Hollow World
Running away from home and stowing away on the wrong ship, Emilie embarks on a fantastic adventure.

Emilie learns that the crew hopes to use an experimental engine to journey to the interior of the planet, but when the ship becomes damaged on arrival and evidence points to sabotage, they encounter the treacherous Lord Ivers, along with a strange new race.

Can Emilie and her new-found friends possibly reach the surface world again?

Emilie and the Sky-World
When Emilie arrives in Silk Harbor, Professor Abindon, an old colleague of her friend Lady Marlende, warns them of something strange and potentially deadly in the sky, a disruption in an upper air aether current. On further investigation they realize it's a ship from another aetheric plane.

How to determine if it's a friendly explorer, or something far more sinister? Nothing less than a journey into the dangerous air currents will do.

Join Emilie and she navigates the strange landscapes of the upper air, and the deadly menace that inhabits the Sky World.
