Suspense is essential to propel a plot forward. It’s what fiction is made of as readers want to know, what happens next? An effective way to build suspense is to withhold information, make the reader guess, then reveal things later. That’s exactly what The Invisible Library sought to do. However, that for me, also was the downfall of the book. Too much information was withheld, to the point that there was little for me to hang on to. Instead of wanting to know what would happen next, I found myself asking what the point was.
