Flights and Chimes and Mysterious Times
I did find the main character a little difficult to like. Jack wasn't particularly interesting and, for much of the book, merely allowed himself to be pulled along by the actions of the other characters rather than to be an active component in the plot. This did get better in the second half of the book, once Jack falls from favor and learns about the darkness that really lurks in Londinium. I also didn't really connect with the two adults characters, Dr. Snailwater and Xeno, but I loved Beth. It is strange, that, despite being the only character who is not quite human, she is the most fun and caring individual.
I did have some issues with the ending, but only in that I wanted a little more information. I would have loved to discover where the Lady came from and why she never ages, but I understand that this was not necessarily important to THIS story. Perhaps a prequel or novella would satiate my curiosity.
Flights and Chimes and Mysterious times features really lovely writing and a fun story. I am still not a convert to the whole steampunk genre, but this is a much more enjoyable example than many of the others that I have read.
