Highly recommended.

Delsea has written thoughtful and engaging Lucius/Tonks fic before, but The Blue Vial, posted at HP Rare Pairs, takes her writing to entirely different level. Dealing with war, rape, survival and redemption in a both understated and yet emotionally rich way, she brings Tonks to life. I have rarely seen the idea of personal identity and motivation of a rape survivor handled so interestingly, with room for human failings and morally grey zones without succumbing to bleakness. I suspect that this may be triggering for some readers, and others may find themselves interpreting Lucius' actions differently from me (messed up but ultimately sympathetic as another victim of horrible circumstances). However, I hope you give it a chance.
