Non-canon content
A few scenes from the novel have been retconned on the show:.
 * Joe Wilson is implied to be alive and missing in the season 5 finale. In the book, he was accidentally killed by Slade during an outburst from the Mirakuru.
 * Oliver plants Slade's old, damaged mask on a shaft with an arrow through an eye on the beach of Lian Yu when he returns for the final time in the season 5 flashbacks, saying he found the mask on the shore. In the book, it is Slade who finds the damaged mask on the shore after he escapes the Amazo, uses his super strength to singlehandedly drive a piece of driftwood into the clay and rock, and leaves the mask there with the arrow that Oliver put through Slade's eye embedded in the mask's eye as a warning to Oliver should he ever return to Lian Yu that Slade survived and would keep his promise.
