Best sellers?

Books feature heavily in our house. We have phases of using the library to curb spending but there's no real substitute for buying your own, brand new book. The children seem to love books as much as mr mc and I which is good. Although babba girl is more interested in literally devouring them rather than figuratively! So can you guess which are mine and which are mr mc's??? It's really not that difficult! The bulk of my reading over the next couple of months is going to towards my assignment rather than for pleasure. There's only so long I can put it off...
