That was excellent, mystery writer! I loved your Lucius to bits (from grumbling all through his rescue of Harry, to glibly turning Harry's amnesia to his advantage, to the utterly delicious sex (in a Muggle bed, LOL). But what rocked my socks beyond belief was that he just hands Harry over to the Dark Wizard without a moment's pause - that was one chilling, terrifying moment of betrayal). Still, it made me happy to see his change of heart afterwards.
Decent writing overall, one or two moments of grammar aside. I loved the snark and sarcasm in the dialogue immensely, and Lucius's griping (especially about his own soft-heartedness).
Also, Harry! The difference between Harry and amnesic!Harry was great - it felt like looking behind the hard mask when he lets down his defences for lack of memory.
Lovely conciliatory ending too, with a fun negotiating bit that allowed both to retain their personalities *and* try for a relationship nonetheless. Very nice fic!
