Janet Lambert can write so well and has done such good sub-deb material in the past that it makes us sad to see such skipshed work as she is turning out now. The last two books seem to be uneven beads, carelessly strung. The heroine, ""the loving and giving child"" of the title, member of a glamorous group of children headed by a 19-year old mother-substitute, has a problem sister who is a ""pain"". The largest part of the interest lies in the tantrums of said sister as the family adjusts to the now familiar (for the Lambert fans) atmosphere of Governor's Island. Both girls are accepted into the ritzy ura of Penny Parish' associates. ...You can guess we did not like it, and feel strongly on the subject because it needn't be this way.
