Stacking the Shelves is a weekly feature hosted by Reading Reality. It is a chance to showcase all the goodies you've collected throughout the week, whether they're bought on-line or in-store, an ARC or a final copy, borrowed from a friend or the library, physical or digital, etc.
None of this is shocking. Though, I own a copy of Exploring the Deep. She's looked at it before. And I will probably steal Sinkable from her because I have not read that one yet.
