Wallflower in Bloom by Claire Cook

 Deirdre Griffin is the social media guru behind her brother Tag's success as an inspirational speaker/lifestyle coach.  Then her brother tries to break up a growing attraction between his old high school friend and Deirdre. She decides to use her mad tech skills to get voted on as a last minute replacement for a celebrity contestant on Dancing With The Stars. I thoroughly enjoyed the Dancing With The Stars story line and could relate to Deirdre's constantly being overshadowed by a popular older brother.  Unabridged audiobook.  7 hours 49 minutes. 272 pages.
