I found a few things disappointing about this novel. The pace is slower than I prefer. For every revealed plot twist there is a lengthy period during which the characters contemplate their circumstances, both past and present. Additionally, while I found the mysterious elements of the novel fascinating and gripping, the love story that develops between the main characters is too contrived to be convincing. The Museum of Extraordinary Things, though incredibly creative and astoundingly original in creation and presentation, ended up being a solidly average read for me.
