Sentimental Garden Lover (2008)

Blurb
Love is found in the strangest places and with the most unexpected partners. The men (and cats!) of Sentimental Garden Lover burst into heart-throbbing bloom! A scruffy stray cat wishes for big hands to hold an abused man, and a cute kitten begs for speech to comfort a broken-hearted stranger. Wander further into the garden, and you’ll find close siblings upset by a love rival; a jaded delinquent flustered by a trusting bookworm; an evasive, glasses-hating man; and a president eager to find a weakness in his perfect secretary. For both cat and human, the quest for love is here!
