My husband and I have created a coloring book together, themed around succulents (!!). We published it on December 1 (2015), and it's available on Amazon.com now -- on sale for $6.29. I think it would make an excellent holiday gift, but of course I'm biased. I'm not sure how long that price will last, so get your copy of Succulent Serenity now! If you are interested in providing a review of the book, shoot me an email and I will get you a free copy.
