Perhaps because I am an only child, I am drawn to books that explore sibling dynamics. Nature versus nurture questions fascinate me and if you add in the advance knowledge of the day you are going to die, in what ways would it influence four siblings? This 'First Impression' was enough for me to add The Immortalists to my TBR pile. I am very interested to see how these 'death' revelations, whether true or false shape these family members lives.
