In all the years that Elinora Gassbeek has been matron of the Little Tulip Orphanage, not once have the Rules for Baby Abandonment been broken. Until the autumn of 1886, when five babies are left in outrageous circumstances: one in a tin toolbox, one in a coal bucket, one in a picnic hamper, one in a wheat sack, and finally, one in a coffin-shaped basket. Those babies were Lotta, Egg, Fenna, Sem and Milou, who were swiftly and firmly deemed ‘the unadoptables’. Twelve years on the children still have each other – until the fateful night a most sinister gentleman appears and threatens to tear them apart.
