This is on my for later list because of this review by skygiants on dreamwidth.
"The Door at the End of the World, an ARC of which was passed onto me due to its DWJ-reminiscent qualities... is the kind of solidly charming middle-grade book that exists in a pleasant liminal space full of nifty magic and devoid of any sexuality whatsoever. ..... this is the kind of book where, it turns out, the proper officials cannot at all be trusted, leaving Lucy and her sidekick Arthur to solve the collapse of the multiverse with only the tools at hand: Lucy's organizational skills, Arthur's cheerful willingness to roll with anything, some chance-met connections in the inter-universe smuggling underground, and, of course, the bees. A solidly enjoyable middle-grade read; the bees are a delight and I support them in all their endeavors."
