The first book in the series was a bit of a mess, rescued by an interesting character, Ell Donsaii, and, after a rocky start (and later a completely ridiculous ending), good pacing that lifted it above the norm.
'Smarter' is a lot of a mess - 187 pages in and you could boil it down to roughly 40 pages. To put it simply, Ell has a theory and is trying to create a doohickie, a gizmo, a thingamajig - and it seems that most of the book so far is given over to explaining what it should be, how it may work, etc.
I don't care. For the love of all that's sacred could the author not just tell a story.
This time round Elle is in hiding from the Chinese who want to kidnap her (her disguise: fat pants, a fake nose, and a New York accent).
I don't care, whatever it was about the first book, 'Quick', it has been lost in a forest of scientific blather and nonsense - I'm giving up, it is a waste of time.
P.S. Just like 'Quick', 'Smarter' has a really ugly cover.
P.P.S. I did finish it and it did not improve.
