Just a quick hit to let anyone reading this know that Rembrandt's Angel by Steven M. Moore is out and available from Penmore Press.
I had the pleasure of reading this before it was published and can attest that it's an excellent read. Great characters and a tense situation with a broad plot that runs the principals all over Europe and the British Isles.
It's available in trade paperback and as a Kindle e-book...
