Andrew Stader is the father of Laila and her little brothers. He is a Telepath, which means he can read people’s minds, even when they don’t want him to. The constant flurry of voices in his head led him to drinking and using Telepathic blockers to block them out.
He is first mentioned in the book when Steve ‘Poison’ Paxton comes to Laila’s door asking to be paid for the blockers he sold Andrew. Andrew, however, doesn’t have the money, so he asks Laila to blow Poison off and doesn’t pay Poison back.
He features as a more prominent character in the second novel, Split Second. There his tough relationship with Laila is clear to see, as well as how proud he is of his son, who also inherited Telepathy.
