I want to put a two foot strip of tile around my wood stove at my cabin. It
is going to go on top of plywood or particle board, or whatever wood is
under the carpet.

Do one use an adhesive or grout to get the tiles to stick to the wood? Or
adhesive, then grout the joints. And what keeps the grout joints from
working loose as the floor flexes? Is there flexible grout?
