I've read a chunk of Shift in addition to this chunk and I frankly can't wait to read the whole thing! The science of the dimensions and the characters that inhabit them are beautifully described and thoroughly absorbing. The hard sci-fi punctuated with comedic beats draws me in, but what holds my interest is the characters: Pei, Harrison, Roy. I'm a big fan of strong female protagonists, so I enjoyed reading about Pei's journey. In the short portions I've read, I've already become invested in the characters and want to know how everything plays out for them.
