The Gifted Guy is a website devoted to helping you choose gifts for the guy in your life. This Valentine's Day edition includes ideas like "gaze into the heavens, and each other's eyes." You'll need Stargazing for Beginners by Lafcadio Adams for that, of course.
The site links to a 3rd party seller on Amazon, where you can get it for $32. Or, you can search for it yourself on Amazon and pay much less. Or you can save yourself the trouble of all that, and buy it right here, direct from Idle Winter Press.
