Thin Air by Ann Cleeves (Mystery/Suspense/Adult)
Thin Air

#6 in the Shetland series, this mystery has detective Jimmy Perez searching for the murderer of a young woman from London who at first is missing after a wedding celebration at the far north end of the Shetland Islands. A complex plot with a well-developed sense of place. This was a delightful read with an ending I should have, but didn't, see coming.
