#CallerUnknown from @gillianmauthor.bsky.social and @panmacmillan.bsky.social is filled with moral dilemmas, a thought-provoking read. I’m already completely gripped by my next read, #EyeSpy from @chrisewan.bsky.social and @panmacmillan.bsky.social

Generally they're books that have yet to be released. It's based on Waiting on Wednesday that was hosted by Jill at Breaking the Spine. I can already tell this will have me on the edge of my seat.
