Moving on to the chapter pages, each new chapter has a page of illustrations (from one of the character's journals) and a very decorative chapter title. The text associated with the illustrations is somewhat difficult to read, but feels hand-lettered, like you really are seeing a real page from the character's journal.
The decorative chapter title seems a little too much, particularly for a small paperback. We have an archway with the name of the chapter, an image, then a quote from one of the character's research notes, then a dropcap. Altogether, this page-spread feels very squashed.
