The book pictured above is Furiously Happy by Jenny Lawson. Another laugh-out-loud kind of book with an important topic of mental illness.
Another book, with a very important topic, is Yoga for a World Out of Balance by Michael Stone. He recently passed and left us all with wonderful teachings and some topics of conversation to continue on.
One of my favourite books (though I love so many, really) is Braiding Sweetgrass: Indigenous Wisdom, Scientific Knowledge and the Teachings of Plants by Robin Kimmerer
Let me know if you read any of my suggestions, what you think and any great books you've read.
