I loved the book as a teen, haven't reread it since my 20s but I probably read it five or six times.
The sequels were meh with one exception:
The one about his daughter doing a space startup was fun because I work in New Space and pretty much all the tech stuff she does is real. I was on the first project to use Iridium to send data between earth and above the Karmen Line and we currently have a payload in orbit aboard Vigoride-7 doing exactly that. So when we have Davie and Millie's daughter teleporting herself into orbit and talking to the ground on an Iridium phone which sets off an alarm at Iridium HQ I was like... "Hell yeah, she can do that! And it would."
