Book of the Month
Recommended for beginners to intermediate, this book is a nice one for all it's fresh ideas and modern style.  Ms. Rainey has a calligraphy background, and this is evident in the style of the paintings, as you can see from the front cover.  A little more 'design' than full painting, this book describes step by step approach to many of her famous instagram designs.  Whenever you have a book that purports to 'learn in 30 days' you take that with a grain of salt.  It's the STYLE that I like in this book..  Find this book, and it's link, below.
