* Signed Bookplate * Join Kim and Penn Holderness on talkshoplive to talk about their new book, ADHD is Awesome: A Guide To (Mostly) Thriving With ADHD. Award-winning content creators Kim and Penn Holderness are on a mission to reboot how we think about the unfortunately named "attention-deficit/hyperactivity disorder." As always, they are doing it by looking in the mirror, because they don't just study ADHD; they live it.
