Hi Erik!! We deliberately decided to NOT have a tip function <3 (I could enable it on here as well) so that people can just download the book and not maybe feel a pressure to donate.:/ (Processing fees here too are quite reasonable, so if the authors DO ever change their mind and wish to enable the PWYW button, I can certainly do that! But until then, it's totally free). If someone wants to kindly support the writers, they can 1. purchase the print cookbook (on Amaz*n), or 2. buy Zilla Novikov's ebook for QUERY on this site <3 or 3. Rachel A. Rosen's eco-fantasy CASCADE (on various other sites). Thanks for looking out for the writers ;-; (They, and the illustrator, Marten Norr, are all great people <3)
