The Enclave — Mark Thomas

It's a lovely wall, we've got no complaints there. Allan Ripke wakes on the bank of a tranquil river, surrounded by cheerful strangers, quaint shops, and a towering wall that encloses everything. He doesn't know who he is. He doesn't know how he got there. But no one seems to think that's strange-not even when names change overnight, newspapers print impossibilities, and fog rolls in thick and unnatural. The residents smile, nod, and tell him what a lovely wall it is. As Allan stumbles through the pleasant absurdity of The Enclave, memories slip and identities morph. Is it sanctuary, experiment, or prison? Step inside. But be warned: once you enter the Enclave, you may not leave the same.
