Piece by Piece: How I Built My Life (No Instructions Required)

The heartfelt and funny memoir of a boy who built himself a prosthetic arm out of the world-famous toy bricks.

David Aguilar was born missing part of one arm, a small detail that seemed to define his life and limit people’s ideas of who he was and who he could be. But in this funny and heartfelt memoir, David proves that he can throw out the rulebook and people’s expectations and maybe even make a difference in the world-and all with a sense of humor. At only nine years old, David built his first prosthesis from LEGO bricks, and since then he hasn’t stopped creating and thinking about how his inventions, born from a passion for building things, could fuel change and help others.

With a voice full of humor and heart, David tells his powerful story, of family and friendship, of heartbreak and loss, and ultimately of triumph and success, as he continues to dream big and build a life and a better world-piece by piece.
