Sounds like a mix-up might have happened! I've spent a fair bit of time roaming the sci-fi and fantasy shelves, and I can't recall an author by the name of Daniel Jensen who's published notable fiction. I did a pretty thorough search out of curiosity and came up empty on major novels. Sometimes a name gets misremembered or combined – maybe mixing Daniel Abraham with someone else? It's a common enough name, so there could be a nonfiction writer or academic out there with it, but in terms of a known fiction author with a significant bibliography, I don't think he exists.
If you're looking for something in the vein of what that name might suggest, maybe check out Daniel Abraham. He's co-author of 'The Expanse' series (as James S.A. Corey) and has his own fantastic 'The Dagger and the Coin' fantasy series. His character work is incredible. Otherwise, it might be worth double-checking the spelling or the source where you heard the name.
