This Is How You Lose the Time War

Has a rocky start and picks up decently at the halfway point until the end, where it fizzles back out.
The writing is sometimes poetic, mostly flowery, but overall does well to distract away from the flaws of time travel narratives (and from the fact that you have no empathy for these characters). Some parts are actively bad and really cringe—you can almost feel how active on 2009 tumblr the authors were.
