Starship's Mage, by Glynn Stewart is one of the best space operas I've encountered - Faster Than Light travel is a staple of science fiction to allow for interstellar stories of interest, and is basically technological magic. The Starship's Mage series has them using real magic to provide FTL travel. The protagonist is a mage with extraordinary abilities that has a lot of people after him and the ship he's on (which he's modified in an interesting way). The ship has also previously made a particular enemy, who now has even more reason to be after them. The series reminds me a lot of Elizabeth Moon's Vatta's War series, which is also excellent.

Note: there's a branch of this series "Red Falcon" - books 1 (Interstellar Mage) and 2 (Mage-Provocateur) should be read after the first Starship's Mage book, and the 3rd one (Agents of Mars) after the second (Hand of Mars). Mainly beware that Interstellar Mage (RF1) has spoilers for Starship's Mage (SM1), Agents of Mars (RF3) has spoilers for Hand of Mars (SM2), and UnArcana Stars (SM6) has spoilers for Agents of Mars (RF3).
