Asher's Dilemma - Coleen Kwan
I've enjoyed Coleen Kwan's Asher series. Steampunk is one of my favourite genres. There are so many different things to explore. "Asher's Dilemma" takes on time travel ... and wow!

This is a lovely, lucid and convoluted time travel plot. The steampunk details are fantastic -- and charming. Who can resist a "chronometrical conveyance"?

There is no way I'm going to try and give an overview of the plot. The twists and turns are intriguing, and you need to bump into them yourself. But in trying to avoid spoilers, I can't say specifically how much I enjoy exploring the impact of time travel on the characters' emotional journeys. It's handled really well.
