Three lives weaving together

The main characters in The Clockwork Three by Matthew J. Kirby definitely need to work together if they're each going to get their wish.  Giuseppe is an orphan who scrounges a living by playing the violin; he wants to escape his wicked master and go back to Italy.  Frederick is an apprentice clockmaker; if he can figure out how to complete the project he's secretly working on, he'll be able to be employed on his own. And Hannah, a lowly maid in a glamorous hotel, wants to find a hidden treasure so she can support her family.  Although I wasn't crazy about the ending - there's a fantasy element thrown in that I wish weren't there - I enjoyed the characters, and the author's description of the sights, sounds, and smells of the various settings really pulled me into the story.
