The House We Grew Up In by Lisa Jewell

An easy beach read about the Bird family and their various tragedies which impact on their relationships with each other and with their ability to function in the world as they grow into adults.  The mother is the most complex and well defined character as she is quite unstable and develops a hoarding habit, which is an unusual and interesting theme for a book.  Definitely readable as the plot is engaging and keeps you guessing but not a literary masterpiece or anything which will stay with you in the long term.  The characters are gripping and likeable but not very realistic.  The writing is unobtrusive and easy to absorb.  Overall a readable holiday book.
