Glasshouse

If I were a free person in the 27th century cosmic war crime prison of Glasshouse, the Charles Stross sci-fi mindbender I just finished, I'd probably use a T Gate assembler to back myself up, then create a duplicate version of myself, have my duplicate write this sentence while my other self took a stroll on the beach, then merge the two neural nets into one version of me that contained both sets of memories . . . but before any of that, you have to solve Curious Yellow and the polity; a good fast read, as long as you don't get bogged down in the technical jargon; an exponentially advanced and precocious baby of The Matrix and Inception.
