Eh. Not great, not terrible. I've read a little out of order with this series, so I now only have one more book to read. I'll probably read it just to put the series to bed, but it's not like I'm really loving this series. 
 I think the big thing was listening on audio instead of actually reading a book. With Deep Storm, my only option was to do an e-book. Here and with The Forgotten Room, I opted for the audio option. I'm thinking with The Third Gate I might just do another e-book because this narrator is just not working for me. Lincoln Child already writes in a somewhat dramatic tone, but with an e-book I can control that voice. With audio, the narrator is super melodramatic, and I can't just ignore it. Kinda leaves me rolling my eyes. 
 I also wasn't as into the plot with this one as I was with the other books I've read in the series. With the others, there was an air of the unknown. We weren't completely sure what was happening. But this time, I knew exactly what to expect. It took the suspense out of it. I'm hoping with The Third Gate the suspense will come back and the plot will be more engaging.
