I've seen covers for books five and six, and they are pretty much finalized and ready to go. Both books are currently in editing. We will be probably be looking at 2018 release for book five.
In the meantime, as these two books are on pre-order, I would like to give you a glimpse of their new covers. As you can see, we went for simpler concepts this time. Each cover is given a striking background colour and a lettering colour that stands out from this. Then there is a center concept on each book, capturing one of the most iconic moments or things within the volume. Compared to the covers from their last publication, I feel these new editions stand out even more. The old covers were more complex, but with complexity in an illustration, it can be a bit hit and miss. A huge thanks to Ruth Germon and Tristan Fisher for their stunning work on these.
I look forward to giving my next update soon!
