Lucas Ambrus has never really had a simple life, He had hoped his seventh year would be easy and uneventful so that he could focus on his N.E.W.Ts however fate had different plans, once again Nymphadora Tonks has gotten him into trouble, only this time, it's deadly. An AU version of Harry's fourth year and a much deadlier Tri-Wizard Tournament. OC/NT HP/To be decided
