B2_Sonia_Kretschmar_Strangest_Adventures3 Sonia Kretschmar > Book Covers > B2_Sonia_Kretschmar_Strangest_Adventures3 Part of the “Strangest Adventures” trilogy, written by (then) 14 year old school girl Alexandra Adornetto and relaunched in paperback by Harper Collins in 2011 featuring my design / illustration. I think they make a nice little set.
