Deafening alarms echoed through the home shared by the Potter's and Longbottom's.

'I think that's all of them going!' James shouted over the cacophony.

'They must be here in strength.' Frank shouted back.

'Grab the kids and let's get to the portkey!' Lily said, taking command as usual.

The four of them gathered up Neville and Harry with the ease of a much practised operation, and jogged down into the basement, wands in hands.

They crowded around the portkey.

'Ready, everyone?' Alice asked.

They all nodded, and after a moment reached out.

Nothing happened.

They looked at each other in disbelief for a moment.

'Someone has betrayed us!' Lily swore, and then kicked something across the floor.

'Let's just wait for Dumbledore, as long as they don't know which house we're in they won't have enough time before reinforcements arrive!' James said, trying to avoid a panic.

'If someone swapped the portkey for a dud then they will have betrayed our location too!'

Like clockwork they felt an immense force smash into the house's wards.

'That's Voldemort.' Frank said, grimly.

Lily hesitated for a moment, before coming up with a plan.

'Let's go back upstairs! I'll explain as we go!' Lily said and started to run back up the stairs. 'James, you take the boys upstairs and go across the rooves, there will be someone holding out somewhere, just stay alive until Dumbledore can find you!'

They had reached the living room by then, and Alice handed Neville over to James, smile on her lips and tears in her eyes, as they felt the wards coming down around them.

'And the three of you?'

'Were going to hold him off.' Alice said simply, before Lily could answer.

James nodded and moved to the stairwell, before looking back at Lily.

'What are you waiting for James?! Go!'

James gave her a last stupid grin.

'I love you Lily!' He said and then turned and ran up the stairs.

Reaching the top, he blew the door to the babies' bedroom off as he heard the same happen to the door downstairs.

James didn't hesitate, blowing the window out of the frame and awkwardly clambered onto the roof, holding both babies in the crook of his left hand.

He ran, slipped and scrabbled across the rooves of Godric's Hollow, as the town burned. He searched frantically for somewhere the Order or the local Aurors were holding out, but all he could see was a mess of curses lighting up the night sky.

That is, until Lord Voldemort appeared in front of him.

'Your friends are dead, James Evan.'

James shook his head, taught with grief and fury.

'That's not my name anymore.'

The handsome monster in front of him smiled sadly.

'Give me the boys James, there's no need for you to die too.'

'I'm going to buy them as many seconds as I can.'

Voldemort sighed

'Avada Kedavra.'

James rolled to his left, but a fraction of a second later Voldemort silently used the curse again, and caught James, who collapsed to the floor.

'Never stood a chance at that range.' Tom Riddle muttered under his breathe, and he rolled over James as to see the children underneath.

Two babies were revealed, one wailing and slightly rounder, the other was silent and bore the bright green eyes of both Lily Potter and the killing curse.

'It'll be you then, young Potter, nothing personal.'

'Avada Kedavra.'
