Nice start. The potential is there for much more development of the character's situation. I really like the symbolism of the suitcase throughout. Definitely, you built suspense here. I like it a lot. Keep on writing:)
I really like what you have here; it is defiantly a great start to a good story! You developed your characters very well, you have done a great job creating suspense about what is going on and what has happened. I know this is a work in progress, so it leaves room to give more background on the father and brother's relationship, but I think that the reader needs to know how Lizzy is making ends meet financially with the new move, paying for private school, and not being able to write for freelance. Great Job, and keep up the good work!
