Free Audiobooks and the Riddle of the Sphinx

The audiobook of Chasing the Dragon: Running to Get High is here.  If you are into audiobooks and the natural highs of running, then I've got you covered.

I am giving away coupon codes for free downloads. First come, first serve, just copy and paste the codes below. All I ask is that you message me here to let me know you've grabbed one. (Hopefully, I can then remove the ones that have been used). If they are all gone, message me anyways, and if you can answer the riddle of the sphinx, you'll still get one. If you answer wrong, however, the sphinx will eat you.

Here are the codes
