Things Not Seen

Things Not Seen is a first-person novel written by Andrew Clements and his third novel after Frindle and The Landry News. The title is apparently taken from Hebrews 11:1, "Now faith is the substance of things hoped for, the evidence of things not seen" in the King James Version of the Bible. The book was originally released in 2002 by Philomel Books, an imprint of Penguin Group, but was re-released in 2006 as a platinum edition by Puffin. The platinum edition includes a short interview with Andrew Clements and a redesigned cover.

This book was followed by two sequels, Things Hoped For and Things That Are.

Plot
Robert Phillips, a teenager known as "Bobby," wakes up one day to find that he has become invisible. He reveals his invisibility to his parents, who instruct him to stay at home until they return from work. Bobby's mother is an English professor, and his father is a scientist. However, Bobby leaves the house and goes to the library, where he encounters a blind girl named Alicia.

When Bobby returns home, he gets into trouble for leaving the house. Later, he learns that his parents were involved in a car crash. The police come to check on him, but he conceals his invisibility. Bobby goes to the hospital to see his parents, where his mother gives him money and tells him to keep his invisibility a secret.

The next day, Bobby returns to the library and meets Alicia again. He tells her that he is invisible, and she suggests he use the electric blanket from Sears-Roebuck that caused his invisibility to reverse the problem. Bobby sleeps under the blanket and becomes visible again. Child protection services and the police come to Bobby's home, but his mother lies and says that he returned from an extended trip.

Bobby goes to tell Alicia the news, but she is worried that he will leave her alone now that he can go back to normal life. She expresses her feelings to him in an email and a poem. Bobby prints out the poem and goes to Alicia's house to confess that he loves her.
