Disconnected, Silver Sonder, and Faded Pages are the only stories I’ve read previously from this shelf and I really like all three of them for different reasons. 
Silver Sonder is better if you’re looking for something short and tender in its own way. Faded Pages is a nice summer romance combined with “coming of age”/self-discovery themes basically. Disconnected is the most serious of the three and the most mature in terms of themes.
