Death on the Empress is a murder mystery written for teens and young adults. It is available for free Kindle download from Amazon.com.
I have not read the book so I cannot offer personal comments, but here is the description from Amazon:
In an alternate Britain, where airships rule the skies, fourteen year old Oliver has started his dream job; travelling the world in the largest airship ever built. But when a priceless jewel is stolen, a passenger plummets to their death and an ancient curse strikes the ship, everyone onboard is thrown into mortal danger. But is there more going on than meets the eye? Only Oliver can solve the deadly mystery onboard The Empress.
