WAKE UP! A picture book exploring new life

Life is a continuing cycle of newness, then growth, and then gone: then birth and growth again. I started thinking about that theme of new life and new beginnings several years ago, and WAKE UP!, published by Candlewick Press, is the result.

Sulcatas are always the first one to queue for food.. i normally seperate them cos they eat more and faster than the others. It amazes me how they can even remember the bowl I use daily to feed them.. 😄😄😄#sulcata #torto #tortoises #tortoise #kura2 #kuradarat #turtle #reptiles #reptile #herpetology #pets #pet #petstagram #tortoiseofinstagram #animal #shell #tortoiselover
