It's actually #05: The Predator.

Actually reading #04: The Message.

Actually on 03 The Encounter now, but it's not available to check-in here at Get Glue.

*Actually* reading 02 The Visitor now! Not sure why they only have 5 randomly selected books from the series to check-in at here.

Still haven't finished 01, so sad. >__>

Actually reading Book 01, but it's not available to check-in here :( Trying to see how many I can read before I get sick of them and need to move on to something else!

i'm actually reading book one now but i can't find it to check in to and i'm tired of looking

The elder daughter is describing this to me as she's reading it. It sounds pretty good.
