Bright Unconquered Suns by
lyras. Alice/Frank, Gen, baby Neville, DH compliant
I highly recommend this as an incredibly touching read. It jumps between just before the Lestrange's attack on the Longbottoms and moments throughout the years of the Longbottom's new home in St Mungos, through the (in case of the latter)addled and wonderfully well-written mind of Alice. Neville is an adorable baby, too - this is worth putting aside canon for.
