17-year-old Lewis Hine is a global phenomenon. Diagnosed with a life-threatening brain tumour and water on the brain at 17 months, he wasn't expected to survive. But Lewis proved everyone wrong; he's not only surviving but thriving.

In one Facebook post on his 16th birthday Lewis invited everyone to see how he faces head on the challenges from his ongoing illness, and he went viral. 30 million views later, Lewis now spearheads a campaign, Friend Finder, to make sure no one ever faces childhood illness alone.

In his memoir, Lewis reaches out to anyone who may feel isolated in their lives. After 13 brain surgeries and continual health problems, life for Lewis is a daily challenge. From the sheer physical challenges — he is at high risk of sudden unexpected death in epilepsy (SUDEP) and has a pump in his brain just to keep him alive — to the horrendous bullying he's endured, he shares how he finds the strength to overcome all this and still lead a fun and fulfilling life. With a host of admirers around the world from Elton John to Kid Ink, Lewis is living his dream — even becoming Radio 1's Teen Hero of the Year.

His story will make you laugh, cry and above all, feel inspired by life's endless possibilities, looking at the stars.
