It's very much worth the read, and is really quite the experience to read through in one sitting. It's well paced the budding relationship between Noatak(or Takona if we're going by his alias) and Korra coming off as very believable and is adorable. It portrays the vulnerable aspect of Korra well without not making her seem over emotional or chickified. The first half of the fic or so manages to be heartwarming and cute with an underlining sense of foreboding, eventually becoming excruciating and heartbreaking as they're relationship becomes more and more intimate and serious. This all builds up wonderfully to the end, which manages to be pretty bittersweet and ends only a slightly AU note, but definitely within the realm of reality.
Noatak is particularly fascinating in the fic. This troper was really pulled in by the way the author wrote him and understood very easily why Korra felt so drawn to him. The fic is pretty long considering it was written for a live journal prompt, but can still be pretty easily read in one whole sitting if you have a couple of hours to kill. It doesn't seem to drag in any parts, as mentioned before, the pacing is very fluid. The lemon part of the fic is tasteful and well written, though it may go a little long for some's taste(though not my own).
A recommended read even for those who aren't into the Amorra pairing. It's very well written, playing the bittersweetness and the tragedy to perfection.
