The series (there's ten in all) do a pretty good job at making what Shatner wanted to happen reconcile with the main Trek continuity, although there is still an element of Marty Stu to his character.
The novels are split into trilogies:
The Odyssey trilogy:
- The Ashes of Eden (published 1995) (set in 2293, after the events of Star Trek VI: The Undiscovered Country)
- The Return (published 1996) (set in 2371, after the events of Star Trek: Generations)
- Avenger (published 1997) (set in 2373)
The Mirror Universe trilogy:
- Spectre (published 1998) (set in 2375)
- Dark Victory (published 1999) (set in 2375)
- Preserver (published 2000) (set in 2375)
The Totality trilogy:
- Captain's Peril (published 2002) (set in 2378)
- Captain's Blood (published 2003) (set after 2379)
- Captain's Glory (published 2004) (set in 2381)
and his last work to date,
- Academy: Collision Course (set in 2249)
These books provide examples of:
- Aborted Arc: Academy: Collision Course was to be the first in a new series set during Kirk's Academy days. The new films are pretty clearly the reason this series was retired early.
- Action Mom: Teilani, after she gives birth to her and Kirk's son Joseph in Preserver.
- Big Bad:
- Androvar Drake serves this role in The Ashes of Eden.
- Daddy's Little Villain: Ariadne Drake, Androvar Drake's daughter, in The Ashes of Eden.
- Honorary Uncle: Spock and McCoy both become this to Kirk's newborn son Joseph at the end of Preserver.
- Human Mom Nonhuman Dad: Joseph Kirk, the son of Kirk (a human) and Teilani (a Klingon/Romulan/human hybrid).
- Landfill Beyond the Stars: One is featured in Avenger.
- Multistage Teleport: In Dark Victory, Kirk is kidnapped and beamed through numerous transporter stations (he briefly sees them while he's being transported) all the way to a distant location outside normal transporter range, where he meets his Mirror Universe counterpart, Emperor Tiberius.
- My Species Doth Protest Too Much: There's a female Orion scientist in The Return who has Federation citizenship and makes a point of dressing un-sexy.
